Yeah, my tune is fine. I haven't ran a better time because I haven't been back out in cool weather. I also don't have a 3600 stall, a 4.10 gear, or headers. I ran a 14.28 with only a CAI, thermostat, Corsa, 2500 stall, and tuning. That is no cam, headers, and considerably less stall and yes still on the 20's myself with no weight reduction at all. The NNBS 4.8L with 243 heads, better intake, and bigger throttle body stock is about the same power output as my older 5.3L was stock. I wouldn't even have to use my own truck as an example. My tuning experience goes well past a couple of trucks and they speak for themselves. Look around here, a 4.8L with a 3600 stall, 4.10 gear, cam, bolt on's, etc should be in the 13's even on the 20's.

Better intake and bigger TB. Well again, if you don't need it, it doesn't help. For another car comparison, my Trans Am (w/ Lid, LS6 intake, EWP, 4000 yank, and a catback, stock manifolds and cats) ran 11.73. I installed a FAST 90 and in colder weather I ran 11.71. Again, that's another case where the engine size would have made more of a difference than a 4.8
So while I'm sure this probably has similar peak hp as an old 5.3 I'm also certain that it wouldn't have ran with one stock. This truck was running mid 16s when all it had was a K&N and the custom catback that it has now (which isn't really a good one). I think gaining 2 seconds from a cam, stall and headers isn't to bad.

Unless he has really sticky 20s on there. I can't believe with that they don't or can't spin. Is it slipping in first? It should blow the tires off even with the slightest throttle.

Here's a link to the tune, since for some reason it won't load on this site.

And a screenshot from the log for all those who don't have HPT. I'll get a good log with AFR on a simple config next weekend.
It just doesn't look much like a 3600 stall, but more like a 2600-2800. The RPM starts to flatten out at ~3000, notice the frame I stopped on is at 3188rpms. I would think a 3600 would flash past 4000.

So that was a 1.8 60' in your log? You look to be a few hundred RPMs over IH8FORDs 3.23 log. I take it that's also on the wheels in your sig?

Honestly i bet if you advanced that cam 2* it would make a pretty good difference....
