Unfortunately I'm not able to scan the graph so I'll just have to post the results. Because of my high mileage (124k) my car seems to dyno much lower than other f-bodys with similar mods. My previous numbers and mods are in the sig. I've since added a home ported throttle body and an ls6 intake. My first pull with the cutout open was 333 rwhp.A/F was 12.1. My next pull was 338 with A/F at 12.2. I guess it picked up because the computer made adjustments for the open cutout. My last pull I decided to run my short belt which ended with a 341 rwhp peak gain though I did see gains of 5+ horsepower throughout most of the pull. Is my A/F too rich and what do I stand to gain by leaning it out a little?

base numbers seem fine but adding a ported TB and LS intake should give you a lot more than 5rwhp. Ported TB should give ~5rwhp and LS6 intake should give ~10rwhp. Looks like it definitely needs a tune. As a comparison a local guy just added an LS6 intake to his car wsimilar mods and ganed 12rwhp:

I actually got 10 rwhp, but you're right, apparently I do need tuning...again. Before the intake and throttle body, A/F was set at 13.0-1. I'm now seeing 12.2-1 up top (from 5200-6200) and around 12.4-1 midrange.
