Stock 91 GTA dynoed!!!!!
Mods:
SLP catback
24# SVO inj.
my own tuning(prom)
Pulled 225 hp at 4350
and 315 ft lbs.............
Broken printer so i dont have the readouts but i should be getting them emailed shortly
Worked out pretty nicely since they are rated at 240 and 340ft lbs stock....
And since it was the chi9cagoland chapters buick meeting i didnt feel as bad as i thought since i beat out 3 other cars lol
Everyone was guessing 190, maybe 200 horse and maybe 300 ft lbs i said at least 300 ft lbs and 205/210 horse.....they ate their words and i was suprised lol
Going to have to do it again once i siameses a set of stock runners and finish porting my other stock tpi base :-) gonna go for 250 at the wheels with all ported modified stock components and ditch the sill factory air cleaner

your guess is as good as mine. its something the tranny shop put in when they rebuilt it. the car doesnt shift very hard at all. more like a firmer stock shift than a car that has a shift kit in it. even with those numbers i can barely get tire into second...i wish i would have gone with the transgo shift kit now.

WOW! Those are impressive numbers!
Now, what am i doing wrong? These dyno numbers were BEFORE the headers and chip. The car dyno'd 8 RWHP and 10 RWTQ less after installing them.
If you guys are pulling those power #'s almost stock, making me wonder how much more is left in mine!

Is the SLP Stage II Chip setup for 24 lb injectors? My guess you gan get a little more out of your combo with a custom DIY prom.
I know I have gotten more than a Hypertech Chip out of my prom burning.
