Just got this tuner and i am getting a p1000 code which i believe is due to needing to be driven since resetting the pcm. However I did drive it maybe a mile or so after the tune and it seems to be shifting odd when going 3-2 downshifting and if you a bit heavier on the throttle up to about 50. It seems laggy when giving it more gas as opposed to light then it keeps revving not as smooth as normal longer than before then finally shifts like 5-6k. Do i need to pop the battery for a bit or just drive it a bit and it will relearn. I did the superchips program and did not alter it except for raising speed limiter. I do have a bit off sized tires 215-65-60 for my winter tires vs 225-60-16 stock. Only add ons to the car are the msd 4 tower coil packs and the silencer removal on the air intake. Car has about 130k on it and trans fluid replaced about 20k ago with redline synthetic.
