Maybe someone can help me. I had my car tuned by yavuz, Now on the way to wakie we had a few problems.
1: Car knocked 61 in 5th gear going from 100-120...
2: Car knocked 91 with air con on, going from 100-120 in 5th.
My cars running 10 PSI with standard turbo with a walbro fuel pump stock injectors normal AFM, and the supporting mods.
So i went to the BP filled up 98 like i always do and this time i put a bottle of nulon booster. After this no problems what so ever at wakie i was redlining it and no issues. Any ideas guys? Its got me a little worried it seems when the booster runs out of the system it starts to nock up to 25 sometimes in 2nd 3rd and 4rth should i take it to yavuz again?
