I guess the point to my rambling is this:
I have customers come in alot expecting alot more than what they get for the money, I don't know if you will even notice a seat in the pants difference after putting exhaust and the power commander on. You may be able to tweak fuel mileage and maybe a little better towing driveability, but that's about it.
Another thing to watch for is transmission changes, we have seen a rash of trans failures in Super Duty trucks after chips are installed, because of changes to EPC pressure(Basically governor pressure). It seems that alot of chip manufacturers are actually lowering EPC pressure, yet raising engine performance. What happens next is slippage, burnt fluid, and expensive parts replacement!!
Not good. I have personally done a line pressure test on a Hypermax chipped truck, and compared pressures "chipped" and "nonchipped". What I found is line pressures that were below manufacturers specs with the chip installed. Again not the best scenario to have.
I realize with a power commander you can make adjustments yourself, so if you decide to go for it, just be careful, tranny's aren't cheap.
The reason for telling you this, isn't to shy you away from the modifications you are pondering, I just want you to get an idea of your actual gains.
By the way Gibson exhausts do sound great!!
If you have any questions PM me.
