I am used to having a very firm shift on my 99 F-250 (custom) and the H2 seems to shift real smooth like rolling into gear (1-2) shift? Is this normal? Sorry But I am new to this gas stuff.

 

it's notoriously sloppy. you can buy a programmer that will change the shift firmness.

 

What Programmer is proven on the H2?

 

i have the hypertech programmer, but i've only used it to adjust for tire size and improve shift firmness.didn't see much of a performance gain by changing to the 92 octane tune. hard to make a 6500 lb. brick perform much better than it already does.

 

I have an F-250 with 500 HP! And yes its diesel and 8000#'s I will make this scoot too, its in my blood.

 

I see diablo Sport makes one and so does superchips and jet. I like them in that order too.
