So, swanny, you're a master of the dark arts - you know how to tune an engine.

Q: This math (assuming 15% difference) tells me that:
_____| dynojet | DynoDynamics
stock | 115hp | 100hp
1mod | 126.5hp | 110hp
Will a car that reads 10 hp higher from 1 mod on a DD read 11.5hp higher on a DJ? or is it more 10 for 10?
