91rocks tuned his 305 tbi with complete bolt ons with a programmer and a wideband he has every mod that i have the only difference is I have an automatic transmission. As of right now I have a chip from tbi chips and I like the my transmission shifts now is there a way to take 91rocks bin and mix it with the tbi chips bin and make it work correctly. I believe that 91rocks tune is going to be a whole lot better than the tbi chips let me know what you think thanks for your help.

I don't see why you couldn't put the two together. If you have the hardware and use TunerPro you can read both chips then use what you want from each to make your new chip.

The biggest differences will be the TCC handling. There will also be some minor differences in the idle control and throttle follower. The TCC is the most important, though, as its part of keeping stock 4L60's cool at highway speed. All of this can be taken from your existing file and added into the target bin you wish to use. Make sure you do this before you use the bin as I think the TCC and shift-light share the same output.
