What was your baseline on that dyno? Dont worry so much about the final number, the difference between your baseline and your final number is the important one.

on my cobras, one of the first things i would do is gears, although it did nothing in th rwhp area, it def added alot of low end power, since it brings th powercurve lower and you have instant power. This will def. knock a few ticks off you 1/4 mile

Depends on the dyno. Raw numbers don't matter, gains do. I think your gains are about right for your mods.

The gain does seem a little low. Was the baseline done on the same dyno as the final tune? Were the conditions similar? Does your car run good or is there something in how it is running that is making you question your power numbers? Even on the same dyno the numbers will move around allot due to changing conditions.

A 26RWHP gain with just headers, filter, axleback and a tune is high. Were the numbers SAE corrected on a Dynojet?

Your Base number is high and your current numbers are very good. No way anyone got 410 on an LS2 with just headers, catback and an intake.

Also is your vette M6 or A6? That will make a difference too.

If it's an A6 those numbers are on the high side, if it's an M6 those numbers are about normal.

Dyno numbers

Those dyno numbers are just about right for your mods. I had my Z51 LS2 dynoed after Jeremy Formato tuned it and at that time had the same numbers but the D/A was abysmal at the time--about what you'd have in Florida, so those numbers seem about right.

Dynojet numbers would never show that kind of rwhp with those mods.
