I am very interested to know what you did with the predator to tweak it for the ported TB. I have kooks LTs, catless mids, flowmaster catback, K&N CAI and the bobcat 455 predator tune. I will be getting a ported TB and ported intake soon and want to be able to tweak it on my predator. PM me or resopnd on here if it isnt too much trouble.
The reason for the adjustments to the injector slope on a stock car is they can still be off with mods. Moving the injector slope tells teh ECM the injectors are larger or smaller depending on which way you do. this help in getting the LTFT's as close to zero as possible then you adjust the PE to get the A/F to your requested range.
Nice gains, I wish when I bought the predator for my Formula that it was as powerful as it was when I got rid of the car. The intial once where limited in what you could do, I got mine reflashed and it was a night and day difference.
LOL And you're not going to dole out any specifics on the +/- % adjustments you made, right? I didn't think so.

Guys, any changes he made on the dyno to dial in that car on that day will likely only apply to that specific car.
Each vehicle is different, and one bone stock car may want a slight negative change to the injector slope, where as another may want a positive change.
Use your datalogging functions to see where you're LTFTs are at and tune accordingly, or better yet do like Richard did and strap the car to a dyno with a wideband and tune for power.
