Oh and who ever said that uncatted ls1 sound like ****...well their wrong, this is the best sounding exaust ive ever heard!!! (pacesetter lt, ory, and flowmasters)
That just seems high for bolt ons. What dyno was this on? Like i said you lose hp with the Chokemaster c/b and the 4.10 gear. The numbers you posted are those SAE corrected? i think that those are...

The main thing in using a correction factor is consistancy. If your baseline is SAE, all others should be as well.
Here's some info I found through a quick google search:

SAE is typically going to show lower numbers than STD, but most people seem to prefer it (I haven't really looked into the formulas much to see which is better in my mind, but I chose to stick with SAE). Each standard (or set of standards) is a way of normalizing the data from a dyno so it can be compared to other dyno pulls. Each set assigns "ideal" conditions and compensates for any difference in temperature and pressure. Because the ideal conditions vary for each standard, they will result in different corrected numbers (if a pull is made at the ideal conditions, there will be no difference between uncorrected and corrected numbers).

Don't worry about it though. Did you have a baseline? How much did you make from your mods? Enjoy driving your car, even if you don't enjoy dynoing it!
