i will do that today, thanks you. i actually read your thread thats the reason i replaced the LPFS, to read the value the car has to be running correct?
the exhaust is dropped it sounds louder than Camed vette, i will install the exhaust today, then try inpa. will update back here soon

Edit: now where the heck did i put that cable
