First off, I'd like to thank the OP for providing these results.
Thanks for putting in the time and money so we can see.
I was talking with Terry the other day about intakes, tunes, etc, and we believe that an intake will help those greatly with DPs, and not with those who are stock.
Obviously we have seen those who have dyno'd their stock car with and without the AFE, and we have seen poor results, but I strongly believe that the results are different with my car or any car who has DPs and a tune.
I'd really like this test to be done on a car with a tune and DPs.
If I see a decrease then I'll be the first to say that I was wrong.
