Diablosports doesn't and won't for a looooooooong time. I want to do a 3 inch lift, 33's and change the gears from 3.42's to 4.10's. I'd need to reflash the comp for the gear change, and I want to take out the tm in this truck. It's horrible. Does anyone know of a tuner for the 05 5.3 L33 motor?
Bryan @ PCMforless tried reading my VIN with his tool but it wouldn't recognize it.

Cool! Thanks you two! I'm finding out that 3" lifts are hard to find if not existant. I wanted to lift it a bit, but still fit it in the garage. A 4" would be an inch too tall. I'm still going to do the gears though and need a tune, so I will check those two out.

 

If you get a tune in do post results, my L33 is turning 4.10 axles and is still a turd!

 

Mike,
I had a problem with my truck, so I took out another 05 on the dealer lot to see if it did the same thing mine was doing. It was setup identical to mine, but with 4.10's. Honestly, I couldn't really tell much difference.
I had an 01 Z71 with 4.10's and an 02 2500HD with 4.10's, and my 05 with
the 3.42's now doesn't feel all that much worse. It did feel sluggish up until about 1000 miles, then it seemed to have gotten better. But I did do exhaust and an intake at around 1000 miles too.
I'd mainly do the 4.10's to compensate for the larger tires. Towing with my 3.42's has been fine. No problems yet with hills and whatnot.
I left a message at Nelson, just waiting for a return call.

 

I have removed the TM in my 05 5.3 H.O. using hptuners and I am very impressed even though i have the 342's. this thing pulls nice
