1st i'd contact Alvin at: www.pcmforless.com and have HIM make a chip for you, you won't be sorry, 2nd: visit www.moates.net for parts and supplies for your chip setup, like dual chips with switch control (not having to R&R the chip, just turn the switch to go from stock to performance)... check it out

MAP has to be spot on to run right whereas MAF is more flexible to adjustments on account of directly measuring air flow.Down side is you have to place the MAF sensor ahead of the TB creating a "restriction"
