Wiseman,
The Comp which offers something like 120hp at the ground in a box should be installed with an EGT and Boost gauge.
Also you will need to have a Clutch or an upgraded Auto transmission to handle this extra amount of power.
If you buy the Edge EZ (65hp) you can sometimes get by with a stock transmission or stock clutch, but even the EZ will accelerate clutch or converter wear.
