Got my car to LMR here in Houston on Tuesday and today. Thought I'd share the numbers. First graph is from Tuesday, I max out my injectors (115%@6300) so he tuned it for what he could. When back today with Holley 42lb injectors and got a few more Hp out of my set-up for a grand told of a 21rwhp/14lbtq gain over the TSP mail order tune and she drives like a dream.

Mods:
Stage 1 TSP heads
MS4 cam
LS6 intake w/ported TB
SLP Long Tubes
SLP underdrive pulley
SLP lid & smooth bellow
42lb Holley injectors

No surging at 1400rpms in 6th and no bogging in rush hour stop and go. I think the MS4 cam is a good DD cam for those looking.

4.10 gears should be next on the list,
Let me know what you guys think
