Message	IMO, more people should go by Crank hp (ie bhp), much like car manufacturers do. As all dyno's are calibrated in different ways, for different cars (gas, diesel, drivetrains, etc), therefore, you're whp will always vary, and it is not very consistent for comparison with similar modded cars! - Just a side note for everyone! __________ Version 3.01
