Good stuff anyways. Any gains are better than none.
Can't wait to see the 4:1 numbers!!!!!!!!!!!!!
The reason why we changed test cars was because the previous car had done some changes to his car that would have, made the results of this test insufficient. For example, he went from 17" wheels to 15" wheels, went from AGX/Hypercos to Ksport crap and didnt get an alignment. So we deemed the test not worth a damn lol.
So I contracted out to Jesus, who I knew had a great running car and would be able to do back to back test on the same day. We started at 10am and finished at 3pm. Reason for the extensive time was because the exhaust shop who did Jesus cat back welded everything 1pc lol. We made 4 base line runs and 4 after we installed the header.
Jesus's mods are the following, Nistune basemap, N1s, S&R, 2.5" exhaust, pop charger, msd 8969, and ssac/Trackforged. No tuning was involved at all. The gains I can truly say are from the much better designed secondaries.
I will have videos and dyno sheets up soon, as we ran out of ink for the printer lol.
