Gotcha, so really tell me this though, why would I even need a built trans?? I mean something must not add up... It could have been that the dyno isn't loaded, and my turbo wasn't fully spooled because I couldn't get it to clean up.
Built trans will last and handle the power. That's like saying why put head studs in? To be safe. Plus triple disk converter.
I trap 110-114mph depending on how I launch, trans shift blah blah blah all I know is it makes at least 299 hp 
maybe when I hit 301hp ill hit my 11.9x run ( truck weighs 7100 with my fat ass in it) might try billings with some different tires see what happens

What I don't get is everyone said going off your mph in the 1/4 mile gives you your most accurate hp, but with all the calculators I got anywhere from 450-650 hp...
Im guesing you weigh around 7k, 7100 and with ur trap I say your right around 490 500rwhp unless your tune is dropping rail like no other. Whats ur eighth mile et and mph?
just to give u an idea I weighed my truck at 7076 with 1/2 tank me in it(I weigh about 2 Brians), spare tire removed nothing else
Yes generous.....but it makes happy customers. The dyno I've always used doesn't factor any correction. But with turbo engine they figure 2% loss per 1000' elevation. And according to some, that might be a little generous.

you guys make me want to reweigh mine. I was 6600 with no passengers and low on fuel. with random normal stuff in bed and a gun in the seat. me In it would put it at about 6830 give or take, but I think the zf is about a hundred pounds lighter than an Allison and I don't know if that's dry weight or not. maybe its actually heavier? I weighed it without the dual disc and traction bars to. but had 305's at the time. hmm im gonna go check again.

Remember you're at 4400-ft elevation and nearly 100-degree outside temperature.
Five years ago my Ford ran pretty consistent 13.6s at RMR. I raced it in California the same summer with no change to the truck (tuning, weight, or power) and went 13.0 all day long...
