Yes, dyno'd in 3rd. I just did 3 quick pulls on the dyno to see what it would say. I thought it would be a bit higher but I wasn't going to spend hours there arguing with the machine. There were also SAE numbers that accounted for the environmental factors but none of it matters until I install the tune, I only did it for fun.Wait. Your truck made 334/352 with headers and full exhaust? I get that the truck hasn't been tuned yet but that doesn't seem right. I put my truck on the Dynojet at my buddy's shop. It made 336/343 right off the freeway... no fan, no cool down. Your new exhaust must have really thrown the stock tune for a loop.
I assumed that you dyno'd the truck in 3rd gear as well...
Dyno numbers are all over the place anyway. I've heard stock HP claims from 320 to 340 and usually people only post the highest or lowest numbers to suit their story.
I'll do a proper dyno and tune next week and I'll post all the information.
