I dont know i have also looked for an aftermarket ECM and or a place that can reprogram my stock ECm but im new to this performance thing on wheelers and i dont know any sources.I though they just reprogram the ECM to compensate for the change in air flow?
Yeah, when i get the HMF optimzer do you think it would be ok to run it with th spark arrestor out just until i can get my exhaust?A bigger throttle body means more air can flow, more air means more power!!!!
On a bone stock machine, this is what I would do...
Find a more free flowing exhaust, intake, more aggressive cam, and then a fuel programmer to adjust your air/fuel ratio. HMF should be able to get you going in the right direction
