Mk2 Engine, Exhaust and Induction
Hi all, I picked up my 10 plate st3 3 weeks ago and no mucking about! I got a milltek ultimate cat back on and a stage 1 flash map.
The problem Is im certain it's still boosting like a standard car, foot hard to the floor for 40 in 4 th gear and I'm only getting 1/2 of the boost gauge. Any help...
