Ive got some of my own, but i fancy a trip down your way to show you the car etc so i could maybe try yours out if you don't mind, make sure they don't pick out anything that mine are missing!
Whats the advantage of being richer on boost, purely for safetys sake...?
Last night i got the fuel cut off perfected, altho i don't get no flames on overrun now! (Im guessing 0 spark advance and being mega rich 9-10afr on overrun combined with a double heat wrapped exhaust right upto the tip used to help also)
Still struggling with AE, i've even tried lowering the thresholds and upping the additional fuel and it still flick's lean before evening out...
