I never have to lift the accelerator. Sometimes if I want to shift a little earlier I just tap the Shifter. For the most part it shifts where I want it too. I don't go blast all the time. When I do the mileage drops to 12. I have more than enough power with light throttle to get going and I never worry about a merge.

The only draw back is that it's doesn't like the cold. I let the engine warm up now until the idle comes down and I don't have any problems with surging or misfires like I did when I just started it and went.

I had the jeep dealer install it for me since I sold my house and didn't have a garage. The install plus the actual purchase price was still less than the RIPP. I made the right decision.
