). You are really better off with the stock tune. 
!hpp3!
!hpp3! Drive a hotcam 99Z, just replaced 02's & plugs. Getting ready to take a trip to SpeedInc for Tuning. Car is still running really rich ( had an exhast leak, car thought it was lean, ran wAAAAY to rich, fouled out plugs 
)
I have the hypertech tune (for spark & fuel,) I'm afraid if I run it this rich for another month before tuning and I don't want to replace the plugs again.
Should I remove the HyperTech "tuning" and just leave the t'stat and tire size changes (315's & 275's) on the car until tuning & then just sell the HPP3?
Really need help, car runs soooo good after changing 02's and want to keep it that way before tuning. Thanks for help.
