what or where does the truck or computer read the hp from and how accurate its it??? in 2nd gear im reading 400hp right before the shift and at 4k in 3rd its at 306hp and steady climbing.

i had the stock maf in and it read 365 hp in 2nd and then added the granateli maf and now its reading 400hp so im just wonder how accurate it is thanks, keivn.

 

Its pretty dam inacurate. I dont really think my truck makes 560HP. Well, then again. The computer says it does so it must be true!

 

you cant judge it with the vehicle in drive and reving the motor because mine reads 1250 hp and 1500 tq lol

 

I just let it sit at idle when that number was flying up.
