My step dad has a lifted 07 silverado and the tranny started messing up so he took it in. Well the dealership said it was the lift. its a pro comp that was installed professionally... The dealer never seen the tune just kept blaming it on the big tires and lift.

 

hey guys so what if u get another computer and tune it or whatever? and if something happens just simply swap to the original computer and take it to the dealer...will that work or no?

 

On a 6 speed truck it would work on the engine but not the transmission considering you reall can't change out the TCM in a moments notice...... Unless you like pulling apart the valve body.

Local dumbass dealer has tried to deny warranty work on 3/4 tons because " You have pulled trailer with it"...... No jerkoff..... I bought a 2500 HD to drive around empty it's entire existance. That service manager quit to go run a coil tubing truck..... good place for the meat monkey.

Or just keep telling you "It's Normal" until you give up and go away, lol.

 

oh nicee thats all i care about the motor lol guess ill try that out and see what happens

 

For me, while tuning the engine has big advantages, tuning the transmission is also just as important for me. A tuned transmission is a joy to drive compared to stock.

EDITED for accuracy. Don't mean to post wrong information, just passing along what I've read.

 

Unless that is a recent change for the latest GMT 900's it's just the instrument cluster that stores mileage and hours... Not the PCM. Changing out the PCM should be no different than killing power to the current one in the truck........

 

The instrument cluster is the only module that records mileage in the GMT900 platform trucks and SUV's PERIOD.

 

My denali has 35k miles, it has a mild cam and a tune and full bolt ons. It just recently threw a rod thru the block. I had it coming when I bought the damn thing already modified. More than likely I am going to have to pay out of my pocket to get it fixed. TSP 418? :-D

 

You run it low on oil or rev the motor past 6500 rpm?

 

Nope, oil was topped off and my cruising speed was 70, so my rpm's were between 2,000 to 3,000.
