Brad,

I have the SHM MAFterburner.

I was at SpringZing, the red SE with the loud exhaust. I would have showed it to ya if you had asked. It does 400rpm spacing a/f ratio adjustment from 400rpm to 10k rpm.

SHM will release a spark controller in 6 months. All laptop programmable.

I am very happy with it.
