[QUOTE="03cobra#2, post: 16438808, member: 52057"] Update: I was having trouble getting my frps to log in LiveLink...I did a A/B comparison of a old tune that had it working to my current tune, and went through like 100 parameters and finally found the one that was turned off. Took about an hour of trial an error but finally got it lol....so now my frps logs like it should. Back to my tip in issues. I did a tune that has the transitional fuel tables reduced like 50% and a tune that had most of the failed MAF table reduced by about 20%....loaded them on my programmer and headed out for a drive. Changing the transitional tables didn't seem to have any effect....the rich tip in and jerk was still there. I loaded up the tune with the failed MAF table adjustment and I think I may be on to something! I was only able to do a bit of driving before work today but the car didn't really seem to jerk / buck in first gear and behaved very well in the short amount of driving I did. So it looks like the ECU pulls data from the failed maf table during throttle transitions. I'll do a bit more driving but I'm hopeful that I am close to nailing this thing (fingers crossed) Also I have a under hood ice tank on the way, and I'll be getting it on the dyno next week for some updated numbers. This time I'll be using the Mustang dyno at my work (finally cleared off and ready to go) with my onboard wideband. The goal here is to make sure the AF is good at WOT with cooler intake temps and tweak the final timing if needed (tuner said he could only get a max of about 18* even though the tune is set for about 22*). I have no idea how my mustang dyno here at work will read in comparison to the mustang dyno I got the readings from last week at the shop I took it to. All in all, I would put the tune at about 90% done and I can really enjoy the car now. I love tinkering / tweaking in general and it's really fun now that the car is just about done. I'll post back with updated numbers once I get things finalized. [/QUOTE]
