issue is your injectors, had the same issue + a moron of a tuner with 4 different attempts at the car still couldn't figure out that the injectors he installed were not able to handle the fuel requirement..went from a quoted 302kw on his dyno straight next day to another dyno at 284kw...had big idle issues with the car stalling and revs just bouncing all over the place and fuel consumption was horrible with me getting 300km off a tank trying to drive economically, and car was pinging funny enough..he said idle cannot be tuned..out of all the cars I have had and the mechanics/tuners..he was the worst.. re-tuned with different injectors and new fuel pump only no other mods and max power of 329 on 15psi and set now at 13psi 320kw @ 830nm for safe everyday drive mods, plazmaman intercooler + piping, id 1000 injectors, fuel pump, 4inch dump + cat only.

where are you getting it done if I may ask?
