XCal 2 expectations

[steedastangt]

I got mine from dallas mustang. I have more mods than most people and was running an frpp/svo performance computer. the tune they made for me gave me 2mph in the quarter, a much better/smoother idle, better throttle response, etc. It basically feels like a brand new engine. heres 1 vote for dallasmustang

Well, I installed my 91 octane tune and the car does seem to run better and idle a little smoother. However, they failed to turn off my rear O2 sensors. How do I go about doing that? I have the SCT Xcal 9400 version.

I haven't tried the 93 octane tune yet so I don't know what kind of difference that will make.
