On the UltraPower... I tried it and it did nothing for me. Not power, not mpg. In fact my mpg went down, they tried other programs, went back to stock and they gave me a refund.
I'm now looking into Banks.
We just got back from a 2,000 mile trip with the stock ECM , and we are also happy that we received a refund on the ultrapower ECM tune after a year and a half of owning it.
Our mileage increased almost 1 mpg on this trip after replacing the ultrapower ECM with the stock ECM....and that is with the generator running! :S I could tell no difference in power with it or without it, hence the return.
Banks is the tried and true improvement apparently.
