i heard of this before so i decided to do some research on it. i found that mainly tC owners have been doing this to their cars. seems like they are producing some nice gains from it, even more so with headers, exhaust and intake.
apparently it can control the a/f for those guys who are juicing or boosting and it can control when vvti kicks in.
i didn't find anything for the xB, so I was wondering if anyone had ventured into this tool yet with our toasters?
My buddy had one on a tC for a while. He ran a modified base tune for a while...just something we came up with. He got it dyno tuned which made it feel somewhat better. He took it to a track and ran it off and then on . . . same time.
He sold it . . .
I don't think this really gives you any power, only allows for better control of the a/f with nitrous and other mods.
