For those who want to drag race their manual gearbox (not auto tranny) cars we are providing as an option an additional MAP which can incorporate a fully programmable (you can adjust the rpm and range) 2 Step Boost Builder Rev limiter.

The AEM handles the 2 Step magnificently and it will sigfinicantly reduce your 60 foot launche times and ET. It is very simple to operate.

Program is emailed direct to you when purchased as an accessory for a MAP you have already purchased from SupraStore.com
