I'm looking at buying a bully dog 6 postion chip. The max gain in hp, they claim, is 140. They don't mention anything about torque. Has anybody here ran one of these on the dyno? I was wondering how much the torque jumed up.

Also can the rig be ran down the road at the highest setting or is it worthless? I don't want it to heat up after a 1/4 mile . I have a choice of four settings to have it built with, don't want the 140 hp if it can't be used.

Most of the big (100+ HP) chips I've seen dyno make low to mid 600's in torque....which represents about a 200 ft. lb. improvement over stock.

 

You must be talking about rear wheel numbers right? I thought the 99 psd made 500 torque, but that must be at the crank. So stock they must make 400 at the tire?

 

My dyno sheet says 468 F/LBS and that was at the rear wheels on an OBS, but I think the dyno operator was a lil screwy. I have never been on a dyno to get another. If that helps any.

Yep. Rear wheel numbers.
