So have been doing a bit of logging last couple of days, the car with a "Stage 1.5" map on it from a company called Ecomax.
The car has always felt a bit sluggish over 3000rpm so wondered if it had a boost leak so did some logging.
Can see its not making requested boost so initially thought we have a leak.
Anyway dragged the file off with MPPS and sent it to my mate and discovered its requesting more boost that safe to on a stock PD150 turbo, also the start of injection was dangerously high amongst other things.
Mate sent me a "test" file which is a lot safer and graph looks a lot better, its still got that inital spike but its better and is holding almost requested boost. He's going to work on the file next few days to smooth that dip out!
Car is also in for new suspension today
