I am going to do some baseline tests on my new truck tomorrow night before i start adding goodies. only thing on it now is http3 which i will but back to stock before test,
question is , is there a learn time between mods, I don't think with hppt because it is changing values but with exhuast etc the computer would neeed time to learn new operating conditions. obviously the thing to do tomorrow is test stock and then put the http3 back in and see what happens.
that might also settle some of the debate about it's usefulness.

I can do the same thing later with the http3 , test with exhaust, headers and intake with and without http3.

Thanx David
