I am starting a new post as I am not getting any response to my previous posts see 99 silverado setting p0748 code

Still setting P0748 code with 91 tune sent, is there any other mods available before I tear the drivetrain out of this thing, if not I will try replacing pressure sensor but seems odd works on factory tune.

Again what should I do to run 87 fuel only received 91 tune.

Help, I've gone back to factory tune so I don't tear out the tranny.

Got it

P0748 code gone with new tune sent, can I still adjust my line pressure and not worry about setting this code again.

Thanks
Gary

Yes you should be able to adjust all the settings without getting that code.
