Thanks Superchips. Finally got the truck the way it should have been from the factory.
I installed the 2950 cortex tune after updating online. Have only been able to put about 50 miles on it since but can definitely tell a big difference. I think after I play with it a bit its going to be perfect.
Was wondering how the corvette servo works with the tuning though.
Any advise as far as that goes Ron???
I do have 20 in rims with a tire height of 31.5 and it is input into the tuning.
Also would you recommend the K&N filter for the stock airbox or the K&N CAI with these tuners??? Is one better than the other as far as working with the programmer?

I would recommend to play around with shift pressures. The SC setting is at the middle of the scale.

A Vette servo will shift the trans too hard in my opinion, with the trans pressure changes that we give.

Try out the shifts pressures in the tuner, Max is 20Psi over stock. The preset Sc setting is 10Psi.

Drop in Style in the factory box.
Ron

Cool I'll take Ur advise then.
Time to play with some pressures.
It has been three days now and it feels better.
I Love the way I control the truck now instead of the truck controling me.

Thanks again.
