Stealership replaced my PCM..uh oh. lol

I really think you'd be the perfect candidate for AutoCal then. Justin can send you tunes from anywhere on earth. You could put a different tune on every day if you wanted

You only get four out of service tunes with the Autocal for the time being. It makes sense why though.

I had an EFI Live tune and it's never been right from the start, and I'm tired of taking 90 minutes trips to ECS to have it done. I have 35" tires, 4.88 gears so Justin would have to be 100% certain he could tune my truck and not have warning lights light up on my dash.

I just lost me entire EFI live tune because the dealer replaced my PCM out of warranty claiming it had an internal short.

The ABS/SES lights pop up due to the gears/tires being out of range of OEM. It is a crap shoot as to whether or not the tune will take care of it, as a lot lies within the eBCM. If your previous tuner was able to turn those lights off for you (provided they didn't just disable in the tune), then it shouldn't be a problem.

Previously, the SES light dod NOT come on It was the Emergency Parking Brake light and the ABS light. They would both come on after I drove for around a mile.

It took the guys at east coast supercharging almost 3 years and about 6 trips to get rid of the lights. They never came on for the next 4 or so months, had my transfer case replaced, and they came on a few days later. So not sure it was attributed to the tune, wouldn't seem like it would be.

Yes, sorry meant ABS and ebrake. Not sure why it would come back on after your transfer case though...

Just get an autocal and be done with this madness. I'm only using 2 tunes for my autocal, but he's spent a ridiculous amount of time just perfecting my ECM tune due to my crazy mods. I would not get anywhere near this service with a different tuner. I probably drive the guy nuts.

Order your blackbear with autocal and be prepared to smile. There is a reason we keep telling you this and that justins name is all over every forum that jas anything to do with GM.

Your truck deserves it. Do it!

Def going to do it, thanks everyone. Just hope Justin can tune it so no lights come on. It's a matter of getting the tire size to gear ratio just right. I'm sure he can figure it out. It's actually a good thing I have a brand new PCM, now I can start from scratch.

Just sucks now that my speedo is off, at around 60mph it's nearly 25mph off.

If it can be done, Justin will get it done.
