your problem is the mangememnt lol

it can only fuel enough for 14psi max dangerously aswell, safer at 12psi

my mates went through this kept cracking number 3 piston even on fresh engine rebuilds etc

final engine build he had omex fitted and was the best mod ever to get rid of the crappy rover ecu

dont bother with these piggy back things either as its cheating death of teh engine, think it only lets you run more boost but doesnt give you fuel, as there is no adjustment for fuel anywhere on them

change teh mangement
