Hi guys, I am looking at buying a MAD EFI to bolt on my 250XB. My question is this what can I expect to see in gains.
My current set up is 21XD 250XB 300pm heads and ECU, hydrotech tuner, poppet valve, light flywheel, getting heads cut to 61ccc, cowl mod. Run a TM case 1:75 gears, .5" below pad, 85.5 mph @ 6400 rpm turning an A45 tempest.
All your input is appreciated.
