question?
 

my friend has a turbo 2. looks like his boost is spiking. cause he said he was lagging power at 90mph hauling arse. its a stock 91 5spd anyone have any ideas.

bump^^^

also he grinds in 5th if he doesnt slide it in easily grinds. does it mean the sychos are going????

so he has no power up to or after 90MPH?

Switch to redline synthetic to help with the grinding.
