One more thing I forgot. I actually got the TSB 18-031-05
flash done at my dealer. I told them I was getting poor shift performance at WOT & I heard this would fix it. They charged me $89 bucks but it was well worth it. Everyone that has had it done on this forum, gives it a thumbs up. This is probably what you need to fix that issue.
The flash fixes more than just the poor shift performance from 1st to 2nd. I have read that it smoothes out the shifting from the flashpaq tune. I actually had the flash done a few days prior to using the flashpaq but you can do it at anytime. Just return your car to stock via the flashpaq, prior to bringing it to the dealer.
