Mods: APexi turbo back exhaust, intake, Manual boost control, turbo smart dual port BOV.... Having problem with the turbo mostly in gears 3-5. The turbo spools and the car starts to accelerate then the rpm's jump and it sounds like the car is struggling and the car doesn't seem to be accelerating. Don't know if it's just a boost spike but if so how do I fix it? The problem started out of nowhere and I can't figure it out I NEED HELP..

 

Clutch, maybe?

 

Sounds like a slipping clutch to me..esp in the higher gears.

 

+1 slipping clutch

 

Lol definitely clutch

 

You have your answer. Now figure out what clutch and flywheel you want and start shopping around. If your a wrench you can do this yourself. Evomoto.com has a good DIY writeup in the tech article section.
