Default 03 5.3L TVS1900 Dyno results

Finally got everything running right so I thought I'd post the results (7psi, 429 RWHP and 467 RWTQ with 108F outdoor temp!). Mods are in my sig. Big thanks to expert installer Rob at Strictly Performance Motorsports and final HP Tuners tuning by tuning guru Doug at Dynamic Tuning Solutions. Ultimately I am VERY satisfied with the kit/tune and can't wait to see how it runs in the 1/4.

not shabby at all. I threw your mod list in there for posterity. Mod lists change over time, posting it in the body of your thread will ensure an accurate account.

Good to see those numbers. My plans are basically the same, with the exception of a GT2-3 cam, 4L80e, 06 Radiator and 07 e-fans.

Haven't done the cam yet. Planning to do electric fans though. It definitely is a beast and I'll try to post a speedo vid soon. Can't wait to run it at Fontana this coming October 31st. Oh and it's actually very quiet unless you really get on it.
