Also replaced the stock air box with the GMPP CAI and had to use the vette accessories since the truck accessories wouldn't clear the intake on the new motor.
try to upload the graph to photobucket or a site like it if the uploader on this site isnt working. it sounds like there is some weird stuff goin on.
id say Gm overrated that motor. i do believe that rating is with no accesories. Also 12.4 is leaving a some ponies to be unspoken for. that combo should do around 380-400 realistically
Ya'll I was thinking that na motors performed best 12.8-13.2 sounds a little rich but still kinda weary of that trans, what gears do you have and tire size.

Sending you a PM,I am from Birmingham and I know the best tuner in the area,ive tryed to tell Mitch aka sprayeddenali about the tuner,a friends truck with almost the same mods as Mitch(friends truck only runs a 125 Zex kit) is MUCH faster on a worse track in BAD weather(Cayman Islands) and my friend tunes himself and is inexperienced.The best tuner in Birmingham street tuned my Escalade EXT(only bolt ons at the moment,I have cnc l92's to go on it and a 408 short block being built) and my OBS 454 Vortec truck(45 rwhp gain on his dyno)He does all my newer American car tunes and I try to send any local LSx/Mustang guys I can his way because he is that good!!.And I tune my stock ecm Grand National,my FAST XFI equipped Grand National,and my 2005 E55 all by myself.I am more than capable of learning to tune the LSx but the guy does such great work and is so cheap,I am not going to waste my time!
Hesco's Land and Sea dyno reads a bit low as well.They are good people and do great work albeit very costly.I have personally had them do a few jobs for me when I was younger and didnt know much about working on cars,they all turned out great.I also know the manager Jeff personally from back in the day street racing.Hell,back then he was just a tech.We do have talented people here in town,most of them being 1 man shows though!
CHECK YOUR PM's IF YOU WANT TO FIND THE HIDDEN HP!!!
3rd shot at posting dyno
