    Trouble with suddun surges

    Had my car cammed for the past 400miles or so and getting it remote tuned by gpi. So today i took out my slicks and put on my 1le stocks abd flashed my 2nd revision. All of a sudden from the night to the morning this problem started. You can feel like if im stabbing the gas making the car surge continuously all the way to around 60mph. All while the surges drops my afr down to around 13.5. I logged this if any one wants to take a look at it. I've flashed the old tune back, replaced my throttle body, disconnected my battery, did a tb relearn all to no vail. Ill be getting a new maf sensor and a new pedal position sensor this week to see if it fixes it but idk if this might cause this? If anyone sees something such as a vacuum leak feel free to tell me. The "wot towards the end" was when everything was working and the "short drive problem" if the one i took right now.

    Won't do any good throwing parts at it. Problems in the tune. Watch torque source.
