Hey all, as title stated.
Just recently had my car Maffless tuned by Oztrack Tuning and now experiencing some unusual acceleration when im going down my gears when the revs get to 1200rpm. The acceleration is only for a quick second and makes the car jolt forward the goes back to de-accelerating, happens in all the gears but if i speed up in a gear (e.g 4th) then throttle off it wont do it (still in 4th) but if i stuck it in 3rd after and allowed the revs to go below 1200rpm the engine will try and bump up revs/jolt forward then revs will continue to go down after. Ive emailed Steve from Oztrack and he seems to think it could be a tps fault. Hopefully ive explained this well enough for all to understand. Any suggestions would be great. Im going to put my old pcm in and see if it still does it because its only started doing it after the tune.
