Having looked at the graphs for Apr and Revo, the Apr has way too much torque for me and comes in too early. The Revo follows standard at the beginning then mirrors the standard map which IMO will be more sympathetic. Hence will be going for Revo, but will wait for stage 2. Any ideas how long that will be?
Voids the warranty increases the insurance. If you have to ask that question go buy a tuning box instead mate
