whats wrong ?? I seem to be missing some HP.... i dyno my truck last week and i only made 240 rwhp setup is in my sig...

 

tuning!

harsh driveline angels, big tires, steep gears and sloppy stalls are going to take their toll.

 

my driveline angles arnt bad really...and you think the rest lost me about 90 hp or so....

 

what a/f ratio was it running on the dyno?

 

no, not 90hp. thats for sure.

 

it was running 17.5.....lol but it is now running 13.1 a/f

 

its just frusterating that a feww people on here are running hte same stetup as me minus the lift and tires and they are getting anywhere between 320-340....

makes me want to sell my truck!!!

 

17.5 is pretty lean, correct me if I'm wrong...

that could easily be why you didn't make the power you were expecting. also, what kind of dyno was it?

 

i'm surprised the engine still runs at 17.5:1...thats like, pushing the limits

 

yeah. im surprised you didn't overheat on the dyno. did you mean to type like 15.7, cuz that's more reasonable but still a little lean.

13.1 should be a good number for your truck. there's something whack about your tune I guess. who tuned it?
