i dont know whats on my car

[ihaterice]

i have know idea whats on my car. the guy i bought it from had it 6 months in that time he added no performance parts. all he did was overhaul the engine with 2k in paperwork for proof. so heres whats up. it runs 14 psi most of the time but it will creep from 15-19 in 3rd-5th with no fuel cut at all. also i ran some 0 60 times and they came up pretty close my fastest being a 4.91 my slowest being 5.7 my average was around 5.2 are these times normal for an almost stock gsx? mods in profile. how can it handle 19 psi with no fuel cut? is there a way to tell if i have a 190 or 550's? can u look at them and see a diff. between stock and not stock?

any questions fell free to ask

Your 3 inch exhaust is going to be the problem for your creep. Only way to help this is to port the crap out of your o2 housing and wastegate. And you might be able to reach 19psi on the stock turbo without fuel cut but you are going to be right on the line. Most of the time fuel cut is a direct sign of a boost leak. Overworking the turbo and not getting the air to the motor. 19psi on a T25 isn't doing anything anyways since they run out around 16psi. You can tell if it is a 190 by simply lifting the seat and looking at the connector on the fuel pump. Injectors will be blue tops if they are stock...not sure what else, different brands look different. They usually will say if they aren't stock though.

Second gen injectors are black tops arent they?

It's pretty hard to hit fuel cut on an otherwise stock car. Usually you have to have an intercooler or something of that sort to start to hit it.

you can hit cut with more boost.

like stated above, 3 inch exhaust will creep like a whore on small turbo's
I dont see your cat hitting 19psi with stock pump, but and pump and stock injectors Mabye.
a 190 pump and stock injectors can hit 19psi without cutting in good conditions, but if you had 550cc, and dont have a fuel controller, it would run like complete as$scrack
