I have a cam and full-boltons for refence and an M6. I'm thinking of swapping an LS6 for LS1 intake myself. I think the power gain would be about the same with the all the mods on my car... around 20whp or so.

after ls6 intake 342/362 no tune SAE was .95 this time and i had the cut out open

It was dyno'd at TTPerformance in north jerzy

Reason I'm asking is because I need to get my car retuned for CA emissions but I don't want to do it put the LS6 intake on and then retune the car again, plus I am just generally curious because that did not seem like that big of a gain.
