New Dyno numbers after tune

[Hay Hauler]

I did some searching on ls1tech and came up with one guy that made 357 with a lid and catback. thats around 33x-340 range off the show room floor. What ever lets just forget about it and go on!

Not as much as I had hoped for, but better than before!
331 hp 352 tq-After headers, exhaust and more tuning I think it will make somewhere aroung 380 to the wheels.

Damn good #'s Hay Hauler. I'd like 330 at the flywheel.
After reading other threads to see your mods it became believable. I'm about to do cam swap on 5.3 for some gains, but for the near future I won't be a real LS1 truck. What transmission are you running, I'm concerned about my 4L-60 holding much more power in an ex cab truck,I do pull a horsetrailer and work my truck daily.

Your trans should hold up fine, but I have seen them go with not much more than stock setups. My trans fluid is a little burned, so I am sure the clutches will go before to long.
