Yeah after 3 yrs i wouldnt go messing with a car like that myself, drive slow so everyone gets to see

Ah with that steel gasket the engine should take 1bar which im guessing is about 250bhp...
so set the boost to .8 or.9 bar and dont mind the overboost
The wossner pistons with lower compression, steel gasket, walbro pump and other stuff on my car and i still wont go over .8 bar on my car and i didnt put anywhere near as much work into mine as you did in urs so i understand why u just wanna take it easy driving her, i hope everything goes well for ya!
