Hey guys, last weekend with the help of Christian I replaced my tappit cover gaskets, ignition leads and fuel rail seals... I also tightened my front pipes up as they were leaking.
Even since we did the seals and gaskets ive been having some issues under boost. It backfires at about 4-4500rpm under WOT and can be heared and felt pretty clearly in the car. Feels like a flat spot.
I can also smell very strong fuel under any boost, but on idle it doesnt smell fuelly and under WOT above 4500rpm the fuel smell goes away again till revs drop again and feels underpowered all thro the rev range. Under light throttle and letting the boost spool up it smells very fuelly but also the car feels like it pulls very hard almost like WOT...
I havnt had much time to scope it out yet but I had a quick look and couldnt see any fuel leak or smell anything untill I reved it at throttle body then I could smell alot of fuel but still no visual leaks...
Anyone have any ideas wat the issue could be?? I have already done an ecu reset which stopped the flatspot and backfire for only a few days but car still felt really underpowered still and very fuelly smell was still present...
