Ok, first off I was driving the WRX today (mods: gutted uppipe, turbo-back)...I was getting on the highway and while I was in 3rd gear at around 5-5.5Krpm the car like hit a wall, so I burpped the gas and it was just fine.

Then about 20 minutes later I was getting off of the highway, romped on it, and again the same thing.

Later I took the car to a friends shop up hear in Bloomington and he said that the car threw a overboosting code. He said that I was likely getting boost creep due to having a very free-flowing exhaust and the tiny TD04 wastegate...

So the reason I am posting is to see if anyone has ever heard of this happening with so little mods, and whether it would be better to port a stock TD04 or if it would be more logical to put a VF39 on the car(with supporting mods)?
