Hi
I've been on the forum for a while and have been reading a lot and learning a lot. this is a great place to learn from. anyways i have a problem with my car and i cant figure out whats going on. its 5.3 , s475 , 80lbs , early z06 cam and 4l80e , i got the car to run and drive pretty decent started with 7lbs and got that somewhat dialed in. a friend of mine convinced me to up the boost to 14ish and we did that got most of it dialed in , the car is doing good, getting faster and its fun but here is where my issue comes in. once the car gets up to around 195kpa and around 6k it goes rich around 10 afr and no matter how much i pull fueling from the ve table it wont change a thing. i replaced valve springs (had old and tired springs) thinking the boost is opening the valves but still no change at all. I am still new to tuning but i will try and answer everything i know thank you!
