You can see that I still had to resort to a piggyback to address the top end working within the constraints of how the chip describes the shape of this transfer function curve. Also used the piggyback to further fine tune my idle, but without it I had an OK idle and nice part throttle. I left plenty of headroom to allow for big horsepower.
From this experience I would say that without going beyond modification of DME tables or adding silicon such as what Vitesse have done, you need a piggyback for a MAF setup to get a proper tune.

Im running a set of full race chips from SUPERCHIPS. When I did the set up I also at that time did the mafterburner,turbo,injectors ....etc toooo many otherthings to list. I will also go in on sayin get a piggyback set up and be done with it it's very simple to get a decent tune in for "normal" driving.
