[QUOTE="Guy, post: 1105804, member: 22717"] [b]Boost[/b] According to JMS... They get 5 psi of boost out of their boostmax. 40-60 wheel horsepower is going to be true. The only thing that is a little deceiving and would be better with a custom tune is the boost increase is not uniform across the RPM range. In other words, you feel the power difference in that 3500+ RPM range. With a custom tune they are able to get more performance across the whole power band. For my purposes though, for the price, and to not flash the ECU it's worth it. It does have an adjustable boost knob. The pedal max does what it claims but the truth is it mostly just takes the slop out of the pedal. It has some drawbacks as you lose fine control over the power spread. Like... if it's raining and you're in 2 wheel drive... you'll inadvertently spin the rear end out. Same for snow. It would not be ideal for off-road but you have a knob to turn it down or off.
