A question for tuners ???

1030 Views 3 Replies 3 Participants Last post by  Northwest Coal Roller
I see a lot of guys making 50hp tow tunes, 80 hp tow tunes, 150hp race tunes and so on, so how do you know the HP for the tune when you create it? Is it just based on what you know a truck with similar modifications has will do or is there something in EFI that tell you this?

Well back when my tranny was stock and after I limped it 6 times... My 160 tune put down 451 on the dyno, even on 35's. But like said above most tuners have done it so teasting that they know what power there tunes will make
