I dont know if this is possible. But since I never go into the boost part of the load curve, is it possible to expand the points to where it doesnt use the boost part and have it all vaccum. therefor there are more points in the range of 00psi to 25" (i think its 25)

 

With the new units, the dealer will be able to move the load points around as required, so they can all be in vacuum for an N/A. Current units have a few options. If it's configured for an external map sensor, you can install a 1-bar GM sensor and ignore the pressure readings (i.e. 27 psi at atmo) and tune it like a Haltech's "Bars". If not, you gain a couple of points of tune with the ECU in TPS mode (versus MAP mode). Really, we've not found it to be much of an issue, having good luck with a even 3-Bar MAP equipped unit on an N/A FC.
