I looked at your tune in the other thread you had and wanted to give you my .02 cents, it's fairly clear in the tune why your aftermarket converter is running erratically, your converter is using the factory verter locking approach with an aftermarket verter, if you keep running that approach, your trans would overheat, and eventually fail. Yank uses a very good material in their locking clutches, but it's not what the factory uses, and thus, won't live as long as the stocker with the factory locking approach.
Also, you have a big block of timing in your timing table, 23.5* fix for the most part, did you know about this? your timing map is flat like the Bonneville salt flats... except at 4400-5200 where it goes to 22.5*, also i don't know what your tuner wanted to accomplished setting AFR stoich at 14.77, mpg perhaps ?, lol, the car would feel sluggish like this during cruise, really, stock AFR for gas (E0) is 14.68, account for ethanol in you gas, and that number goes down to 14.40 to 14.1 depending on how much ethanol the gas station is adding, so why mess with it this way ?
Trans shift points are stock, they just changed the shift rpm, which would accomplish nothing really other than perhaps confuse the trans at a WOT shift, oncoming/offgoing pressures changed, why would somebody screw with the presets if the trans clutches are stock? other than that, you have faster shift times, which don't look bad, but perhaps the change in the 3-2 power shift torque inertia profile is what is giving you torubles with the 3-2 downshift,
If they have done this 5 times already, and haven't realized their little mickey mouses yet, they're more likely copying and pasting changes in the tune, and shooting the arrows in any direction to see if they can catch a bird
, the MAF seems to be tuned, but who knows what your fuel is doing without a WB to verify. i've seeing tooners just add 5% to the entire table and called it a day. The ones in Michigan are famous for this.... and they call it a tune, lol.
