Boost Creep And Misfire....

[lcy]

Hi ppl,

I am having some problems with my car right now... The boost is not holding and its misfiring aswell. its been in and out of the workshop a couple of times (mostly a week at least).

Trying to diagnose the problem but still having the same problem every single time.

Just had my car tuned, unopened engine, gt30 internal gate and all supporting mods. Service was done and sparkplugs changed, coilpack changed(splitfire), using AVCR(all lines checked, solenoid working), Power FC tuned to 350hp 1.1 bar.

When i give the car a rev, hits full boost it either misfires or doesnt hold the boost. (Check AVCR- it goes to 1.3bar!!!!!)

Goes to low setting 0.8 goes up to 0.95bar. Feels like lack of power even when it hits full boost(without misfire).

mechanics done has checked everything but it still does the same thing everytime.

Any ideas??

Thanks inadvance!
