So I believe I have the wiring hooked up correctly. At least it's hooked up like my 1997 9000. Which runs absolutely amazing. Now talking about the 1997 when you hit the break in the 1997 at full Boost the Boost backs off which I believe is correct. Now referring to the 1998 car which is the one that is causing the overboost problem when I hit the brakes and it I am still at wide open boost. So from that information that I have found out referring to an old post from Ari, I have blown one of the mosfets in the ECU and it's the one that is causing wide open boost instead of base boost. Does that sound correct? I will be looking at changing out the mosfets either tomorrow or Saturday I will report back but anybody else chime in and thinking that is correct let me know please. Thank you a little bit more of an update. What the help of chat GPT I was able to test the original ECU that was in the car with the T5 valve two of the mosfets are blown. Tomorrow I will test the ECU that has the upgraded t7 valve and see if those mosfets are blown I'm going to assume they are considering if you hit the brakes I'm still at wide open boost that's not supposed to do that.
