So I was finally able to dyno my car a week ago for the frist time...Boy was I wrong about how much power I had.:cry:
List of mods:
Injen Intake
RRE UICP with a 1G BOV
RRE downpipe (No Cat)
Apexi N1 cat back
Both 3" in
MBC set at 15 psi

Now I know this isn't that much of mods but i mean i thought it would be enough to at least get it up to 180-190 whp..So I had 3 pulls and my first one was my best. At about 4500 rpms it hit 145.9 WHP and held it in that area till about 5200.:notgood: For tq i got about 180-190 ft lbs between 3400 rpms and 4500rpms. I talk to the tuners and they said it was heating up to fast and the knock sensor trip so the timing backed off.I'm getting enough fuel too so i was hoping for somthing a little bit more..Plus it is the great stock T-25 and won't hold boost till redline...Oh well! so right now it looks like i'm gonna be swaping out that T-25 for a Big 16G that is proted and a 225 walbro pump and 660's injectors and a S-afc and FMIC..and with that i will hopefully be making alittle bit more power..:D

invest in a datalogger and a wideband O2. While you're at it, boost leak test and leak down test.


Get your car up to stock spec hp before throwing in even more fuel. Obviously somethings wrong. Some seafoam will tell you if you are leaking exhaust before the 02 sensor or turbo.
 
Definitely do a boost leak test, check compression, etc. I agree with the above said, a data logger would be a great investment.
