Car acts like you are hitting a rev limiter or something

is this on a stock ecu?

or k-pro / AEM etc.. ?

 

I went back to factory when i noticed this problem so I could trouble shoot the problem.
Yes it is turbo charged , but I unhooked the greddy e management ultimate , put my stock injectors in. unhooked my turbo from the intake and regapped my plugs back to factory standards.
so basically its not using the turbo, Trying to get this working right .

 

Dude, just reading your two threads makes it very clear you need to STOP. STOP, ask some intelligent people how to proceed, take your car to someone locally that isn't a dipsh*t, get new management, buy parts that aren't junk and you'll be good. At this point, I'd start over. Take all that sh*t off, recover what money you can, then do appropriate research and build the car right. That or I'll trade you your S2 for my GT3082R built LS/Vtec delsol that's done right...lol.
