If a CAI is installed as the first mod, you will see dramatic gains. Same thing if you dyno after any "first mod". Everything else is incremental.

Actually thats all James had done was the Gen 3 install and he had like 1hp gain from the last dyno peak and little to no gains throughout, again its due to the heat and humidity.

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.
