Hey guys, just purchased a 2000 r34 gtt and am pretty sure something isn't right with the waste gate or turbo. Car is pretty much stock besides a race pro inter cooler and 3" exhaust from turbo back running on stock boost (what seller told me). when accelerating , even at low revs my boost gauge tends to spike right up roughly around 18psi according to the stock boost gauge but doesn't feel like it and it sounds as if my wastegates venting the whole time im cruising on the throttle. Any ideas on what to suss out first? am a newby to boosted cars tho if someone can point us in the right direction I have no issues fixing it.
