a guy I know has a 2g eclipse. Stock turbo, stock fuel. He has Greddy hardpiping, and bov. It is a 97', and he hits boost cut at 10psi. I looked at it yesterday, and
his knock sensor wire was completely gone. I took the sensor from the motor I have in the garage. He said it idles a lot smoother. But today he called me back and said it was hitting boost cut again. Do you know what it is? Also has a stock Boost controler. Im not sure if I put this in the right area But i could realy use some help.

1.) There is no "boost cut".

2.) Fuel cut is only a function of the amount of air being drawn through the intake. How hard is he beating the living crap out of this car?

You need to check for boost leaks.
