Pls help, I'm getting hiccup!!
 

I have recently gotten my evo6 and have the following mods:
- walbro pump (idle fuel press is at 3 bar/at 0.0bar of boost it is at 3.5bar/at 1bar of boost it is at 4.9bar)
- exhaust
- hydra
- avc-r
- evo7 standard coils
- NGK Iridium no. 8 plugs

The car was tuned at 1.5 bar 2 wks ago without any problems. But the day the tuner went back I started to get some hiccup as I run boost 1.3 bar upwards (below 1.2 bar the car runs fine). This is not a very bad hiccup but I think it is blowing out the spark and I get this around 2-3 times as I go up the rpm range. The day my tuner left I was trying a couple of pulls in 1st gear but the car hiccuped quite bad and I later noticed that the tank was almost empty (no fuel) :mad: I'm not sure if this did some damage to the engine so it's causing this hiccup problem or not.

Here's what I've done to try to fix the problem:
- changed spark plugs to NGK no. 9 and Greddy no. 7 (gapped down)
- adjusted dwell from normally 3.04ms to 5.08-6.5ms
- changed to evo7 coils as my previous evo6 coils was damaged (somewhat melted) when I got the car.
- advanced some timing (because where I am the fuel quality is bad and ign seem to be a bit retarded at high boost)

None of these seem to work and I'm now out of ideas on where to look.

Appreciate your help on this thank you

:crap: :crap:
