Dynamometer Results & Comparisons - How do these numbers look?

This is on my 01 vette with the M6 I made 269/280 uncorrected 316/334 corrected(or is it the other way around???) I'm at 5200ft above sealevel with the DA being in the 8.5k range best run was 13.8@104. Mods when dynoed was intake and catback. Most C5's dyno about 250-260 up here and run low 14's/high 13's from what I see. If I convert it using this link http://www.carcraft.com/techarticles/116_0306_nhra_drag_racing/index.html it state that at sea level I would run 12.92@111 does that sound right? Most other guys at sea level with those mods seem to run about that maybe a 1-3 mph less. I have raced a few modded sti's and evo's that dyno about 350-360 to the wheels and I can inch them out but they stay right there with me from a roll for a few gears so my numbers seem about right.

here are my dyno sheets first run made 310 second was 316 nothing changed this was just to get a base run no tuning.

Since these runs I have installed a ported TB, removed screen from maf, vararam air bridge, smooth coupler(I know whoopie) and relocated maf closer to TB. I want to go tune it to see what I pull but how do they numbers looks? Again real numbers for this elevation are around high 260/270 hp and 290's torque.

When I was in the ATL at commerce dragway most C-5 vettes ran 13.5 at 105mph, so your not to far off, depends on your hole shot and the type and wear on your tires
