Hmm well ive got two fuel ecu's.
No1 boosted fine but gave me a rev limit of 5.5k
No2 gives me a 7k rev limit, but over boosts like crazy.

Simple enough to sort the 2nd one out, but i actually prefer the 1st one (engines never at high revs, so much less chance of going bang.)
I had it RR'd on the 1st one, and produced 186bhp atf and 234 lb/ft of torque, with just a chip,filter and exhaust, all at under 5.5k
