Re: boost

the standard ecu may have been mapped for the new engine, but from what you say sounds like it may have not have been.

need to get it looked at by a specialist to see whats going on, get it on a dyno see what the fueling is doing.

Re: boost

tbh it sounds like you need to keep it off the road till its sorted properly, upping the boost without makign sure map is right can result in blowing up the engine.

if i were you i'd get the simtek fitted and mapped asap
