If the loss is 4% to 5% reasonably for the atmospheric changes, then we all should be right on the money for gains. 276whp with 4.5% added in would be about 288-289whp which makes sense for a full exhaust or Gen 3 install up from baseline of 276-277whp.

I'm not going to dyno again though until its a reasonable 80ish degrees, now that I got rid of that crap OEM muffler. It feels like the same gains I got with the X-Pipe added in again with straight through Magnaflows added and the rear muffler gone. Hoping for 285-290whp, it definately is fast now.

Why not wait for September and nice cool temps? I agree on your numbers, when I installed my Berk CBE I went from 278WHP to 294WHP under similar temps (low 60's) and low humidity. I then installed Gen3s and showed "no gain" at 95F and high humidity. Something tells me when I do another pull come September, I'll be over 300WHP.

The Berk CBE sounds great. I'm not surprised you got that much gains from it. With the 8 month wait I had to go with the Boombop Shop CBE. I should receive delivery sometime late this week or next week, so I'm post a video. But you're rignt, probably will not get another dyno until September-October.

Anybody in ATL have a digital camcorder that they might be willing to let me get an exhaust clip on? Wanted to post it on the site database since nobody else has this setup.
