Tyler, yes, yes I am

I actually like the way it sounds with the flows, but since the baffling or whatever broke, I figured I'd try somethin different

I'll try to get one tomorrow. The baffling bouncing around inside muffler doesn't sound too pretty though

I know it all too well, my flowcrapper took a crap on me when I started putting boost on my truck, all the baffles broke loose!

Well...here's the numbers...
358.2 rwhp
308.6 ftlbs


It did actually make a pull in the mid 360s, but I couldn't find that graph afterwards? Anyways...I'm EXTREMELY happy with this thing. Once again, Tyler has put a helluva tune on this thing. Drives like stock, no surging, NOTHIN...just sounds MEAN! Numbers did fall a little short of what I expected, but not by much. This was only a second gear pull as well...

For those that don't want to read, the setup is...
5.3L bore with flattop pistons
241 casting heads milled .040 and p&p by dtr81 with a stock thickness head gasket
~10.5:1 compression
231/238 .601/.615 113LSA COMP cam
pacesetter long tube headers w/dual 3" exhaust with dynomax bullets
and this thing sounds NASTY

also like to add that we didn't get to make any nitrous pulls because of a faulty fuel solenoid

Wow, that's damn good for a 5.3 N/A. Any vids of it on the dyno or of it going WOT? I love the sound of High compression motors!
