Best tuner for 5.0
 

I'm looking for a tuner that will change the trans shift points on my 2012 GT auto. I find that under light to normal throttle it now shifts up much too soon and it feels like the engine is bogging. Going up hill, for example, under light load it will constantly shift up into 6th and bog then shift down again when more throttle is applied.

I would like it to hold gears for longer and let the engine use the revs that it likes instead of the constant up/down/up that it does.

Any thoughts on a decent tuner for this?

Oh yeah, the only mod I have done is a Rousch Axel back muff.

Tx.
