Thought some of you maybe intrested in this...copied from SVT Performance..
Today we had the NVLOPE (Northern Virginia Lightning Owners and Performance Enthisusaist (sp?)) Dyno Day at Excessive Motorsports in Manassas, VA. I think there were just right around 10 trucks there. There were about 3-4 trucks before mine, and when we put mine on the dyno, the a/f was reading VERY, VERY lean (18.0), so Chris got on it a few times to see if hte a/f would come down and it wouldn't......he played with the chip to see if that was the problem. Well, to be safe he didn't do a full pull with the truck, but before he let off it pulled 345hp/and I think around 420 tq. I wasn't disappointed with that.....Then he put a 02 True Blue with 3500 miles on the dyno and it was the SAME THING. So, he knew something was up. He replaced the filter and the wide band sensor on his A/F gauge that that was the culprit. Pshew. I thought I had some serious things wrong with my truck.
So then, we put mine back on the dyno. I was somewhat impressed with the numbers my truck pulled with the minimal mods it has (see sig). On the street side it pulled 360hp/421tq, and then on the 'race' side it pulled a best of 383hp and a best tq of 461. I was happy. However, it could use retuned and pull some more ponies out of it. It was way rich across the board. Heres the 'race side' dynos.


Before me some 02/03 trucks one with a 5# and some few minor bolt ons put down some where around 396 and another with similar mods broke the 400/500hp mark.
All in all it was a good time.
