After lots of talking we hahn and on the forum's here i was gonna go ahead and dyno my car with the vss mod. Well then we got the bright idea, why not take and get my ecu reflashed to a 2003, that way the port fueler works right. Well thats what we did, and that alone dropped my a/f from 14.7:1 to 12.8:1 big improvment. We then we ahead and did some tuning with the port fueler system. We acctually had to take and dump alot more fuel into the system since the it comes from hahn with the setup they had on there car and i have more headwork done and flow alot more air. Now where at the next big problem, which isnt much of a problem at all. We noticed that after 12psi the turbo wont hold boost. Easy fix though, its just the wastegate, its to small for the boost where running, so im ordering the larger wastegate from hahn and then were gonna up the boost and try and crest the 300whp mark, which shouldnt be much of a problem. Also talking with the guys at the shop that does my work they seem to believe there dyno runs about 20hp less than most other dyno's so i might be sitting on more hp than i've stated, till proven otherwise im gonna go with these numbers. Hope to have bigger numbers soon
Nice, glad to see that we are finding solutions for this problem

so there is ecu differences from 2003 to 2004. how exactly did u get it flashed to a 2003? cuz i looked at your profile and saw you have a 2004.. as do i.

how much headwork? like a minor hand P&P? or a C&C machine port?

yeah internal gates are only good for soo much above their rating. might want to look into a valve train upgrade as well.. as the stock valves will be floating around 17 or so. the stock valve train cant take that kind of pressure.
do u have pics of ur install? how long/hard was it? did u have a shop due it or are you near hahn? any details or info would be more then welcome.
btw, glad to see that everything works. nice to know that hahn is behind their product that much and helps their customers
The ecu reflash was easy, all they(gm dealership) had to do was get a 2003 eco vin number then reflash the computer, total time was around 45 minutes with finding the number included. As far as headwork, its all been c&c machined with a 5 angle valve job. And yeah the wastegate is a 6psi wastegate and they can hold up to 12psi before it blows off, so i got ahold of hahn and it was 110$ for the 15psi wastegate which wont blow off untill around 30psi so i should be good with that. Ohh and before i forget i know i've been asked before and yes i have upgraded the valve train. And last thing, i do have pictures of the install, but its on a throw away camera, and i still havnt got it developed. I'll take and get it developed this week and get all the photo's on cd and put some of them up. As far as the work on the car itself it was done at a few different places. The turbo itself was all done in South Carolina at a shop called The Show Zone. Anyone living in that area i'd recommend going there. They even let me stick around and bug them and help lol.
ya I would LOVE to see 18psi with the port fueler system set up .... and the afr......
let us know !!!!

awesome. glad you got it figured out.
Boosted Illusions(Grooms) - I have the same Hahn manifold and 4 extra injectors (except I'm not using the port-fueler I'm using another device "034 EFI" Same cencept) I have a 2003 cavy, I'm wondering if I will run into the same issues when I get my car on the dyno. You said you had the ECU reflashed. Is there a way to tell if my ECU will be proned to the issues you ran into.

sweet goot to know. a simple reflash fixed everything. y the hell would gm make a change like that
so you did the vss mod to dyno? can the portfueler support enough enough fuel if you pass the 6500 rev limiter or keep going past 105?
so reflashing it to a 2003 would be better than reflashing to a 2002? cuz i thought 2003's were fifty fifty that they would work fine and 2002's never had a problem with the fuel going back to 14.7:1thanks guys
We never used the vss mod on the dyno, saw no need to. One problem you run into with the vss mod is the vehicle dosnt see acceleration so it cant adjust for load settings.
Twisted as far as your set up, you should be good, im pretty sure you wont need to get reflashed. When we reflashed mine all we did was change the ecu settings from 2004 to 2003, the rev limiter all of that is the same, still at 6500.
As far as the port fueler system supporting the fuel past the 6500 rpm range, shouldnt be a problem at all, with the port fueler tune im running now, at the richest point the aux injectors are only at 45% duty cycle. Tuning the port fueler is very easy, its a basic x and y axis with boost levels and rpm ranges. The boost goes from -4psi to 30 psi and from 0 to 8000 rpms.
Did you happen to get a part # for the reflash? this may help others simplify the process of dealing with the service personnel at the dealership.

u never used the vss on the dyno? so did u do a pull in 3rd? or a pull in 4th and just went past 108 with the portfueler? they are 550 cc injectors?
have u been past 6500 or 108 with the portfueler?
so whats your a/f ratio now? is that X Y axis you posted exactly how yours is now? after you did some tuning? just wondering, but why are some of the numbers in green?
Dont have a part number for the reflash, all we did was get a 2003 eco vin number and use that to reflash, and when we did the reflash i think i said this already, but we didnt change the rev limiter, its still set at 6500. The way the car pulls and how fast the turbo spools up i dont need more, i dont see a need to go more than 6200 when racing(at the drag strip of course). And yes, all the dyno pulls where in 3rd gear. The fuel map i posted is mine now with the tuning complete, the colors just represent how hard the fuel system is working i believe, it has 3 colors, black, green, red. I Noticed that lower fuel volumes its black and the more fuel you dump through the rpm ranges it changes to green then red. And a/f ratio is 12:1 across the board under boost. And the injectors in the hahn kit are 40lbs.

is your fuel map THAT much different from hahns since your running a C&C ported head or was it just some mild changes.
oh wow their 40lb injectors? whats the power limit on those with the portfueler setup?
did the same shop that installed your turbo do the portfueler? how long did the portfueler install take
We played around on the dyno for about 2 hours trying to find the best setup we could. Its alot different then the hahn setup. With the machine work on the head my car would flow more air faster so when you'd first hit it, it would go lean fast then slowly come down. I think it would jump up to about 15.5:1 then drop down into the 12's. Thats where most of the changes where made, early in the rpm range, with the 16g turbo im seeing full boost at about 3200 rpms lol. Im not sure as to the power limit on the port fueler system, didnt hahn get like 404 hp out of their car? Not to sure. The port fueler system isnt to bad to install. Its got 4 clips for the injectors, i think one that goes into the ecu, one that goes into the downpipe to watch the a/f. And then a line to monitor boost. With the tuning software you can also record your dyno pulls with the port fueler system, so for the man on a budget you could street tune your car. It really shouldnt take more than maybe 2-21/2 hours to install. The only draw back is that i think im gonna have to pull my intake manifold off to change my oil filter. I was looking at it when we put it on, and well theres just no room there at all.
WE NEED VIDEOS!!!!! damn dude get us some vids i really wanna see how the car runs and how that port fueler is working for ya
i'll make one today, i have to warn you though, all i have to use is my dig. camera so the quality might not be to good.
Ouch... you have to take the manifold off to change the oil filter!!!! I'm not looking forward to that.

thanks josh. glad everything is working good. now up the boost!!!
when u get those pics developed, id love to see them.
Sounds like it's going to be a monster.

Where in SC? Ive never heard of this shop...sounds like a place I need to visit.
Is the Hahn port fueler just the Saab Manifold machined with a hole for the 5th injector?

The shop is in the charleston area. The port fueler manifold has 4 aux injectors in it. Not sure what the saab manifold looks like. Also i went to make some videos and my batteries in my camera where dead so i'll have to do it tomorrow, i'll make sure its extra good
thats the manifold on my car
and thats the front mount
the Hahn manifold is a completely custom, hand made piece. Nothing AT ALL related to the Saab manifold.
