i have slight pinking as my other thread states, n im hoping ive solved this by buying a upgraded fuel pump to match power but tonite i noticed that wen i boosted n she pinked, its like it tripped summat n limited me ta 0.5 bar n if i tried exceedin it, id just kangaroo.?? switch off ignition, back on again n shell boost til it pinks then trip again. shes parked up now waitin for my pump but to me it sounds like im activatin the knock sensor. ( if i have 1 ) all replys will b very much apreciated
