i hate staged packages.. the staged AP packages IMO are identical to the TXS staged packages they had long ago with the unichip.
They are very inflexible if you plan to stray away from thier suggested parts list.

If you're looking for power, my suggestion is to figure out how much you're willing to spend in one shot, pick a realistic power level you want to acheive, pick your turbo and supporting engine management, and buget in for a custom tune.

All cars are different off the showroom floor, HP in a box may work to some extent but you play with fire when the A/F ratios vary.

Last week, i spoke to Dave from Kingpin performance about the staged packages...we both laughed about folks calling in to compare the Cobb or TXS staged packages.., Dave's "stage 1" kit puts out 535 whp! ..im curious what the next stage is..lol.
