I have just urchased a 96' Skyline R33 GTS25T series II. It is stock apart from HKS intercooler, 3.5" turbo back exhaust, Bleed valve, Lowered suspension, adjustable shocks and 18" rims (look really good with the huge deep dish on them).
But my problem is this. Under load (i.e acceleration) in 2nd, 3rd, 4th the engine kind of stalls and flutters, looses power a bit before it takes off again. Bost is kickiing in about 2.5 - 3 grand, but teathers out at about 5.5 - 6 grand untill it decides to take off again at about 7 grand. It is almost like it is missing at high load. I have spoken to a few people and they say that it could be fuel related, others say that it could be electrical. I just don't know.
What I want to know is there anyone who has a idea of what it could be? Any ideas would be great.
