Hey Guy, Will I get a increase in hp if I go +2 in the 0-2000 +1 in 2000-4000 and +1 in the 4000-8000 range. Should I increase the fuel/Air or just leave it at 0. Thanks
To be completely honest, you shouldn't mess with any parameters on these cars unless you know exactly what you're doing when it comes to ignition timing and a/f ratios. I've been a tech for 25 years and I still get Kevin MacDonald of Diablosport to fine tune my new stang.
It would probably be best to contact Brenspeed and ask them. With that said, most mailorder tunes are on the conservative side when it comes to timing, at least the ones I send out are. I'm sure that one or two degrees wont hurt, but I wouldn't expect to feel any seat of the pants difference from it, cuz you won't.
