Actually my car would misfire like crazy. I removed my step 1 colder plugs and I found out that the gap had opened from 0.024 to 0.028. I replaced them with a new set of OEM plugs and now I am waiting for Saturday when I will install a brand new set of properly gapped step 1 colder...
I will let you know how it will go...

well we changes plugs, oil and put it on the dyno...
straight 93 octane shell v-power the car made 344 (dyno dynamics uncorrected) which was around 7whp lower than my original tune but with 93 degrees in the dyno room i am happy. boost was touching 24 and then dropping to 23 all the way to 8000rpm... Power is over 340whp from around 6000rpm all the way to 8000rpm...
timing way to conservative and safe, way less than 15 degrees and afrs around 11.2-11.4...
The car doesn't misfire any more and pulls all the way up top again with no problems...
the leaning out and erratic idle was higly improves with a combination of MAF scaling, idle stepper tables, even with a slight adjustment on the throttle body.
When we too for a drive it felt like it gained 40whp again up top... cant wait to hit the track next week... hopefully no more issues and i will finally have my 11second timeslip...
as far as the idle / leaning out is concerned i will elaborate after a couple of days ti drive the car normally in traffic etc etc... BIG IMPROVEMENT though!!!
Ohhh, also my stock diverter valve might be leaking too...
