Installing Momentum Headers

That is actually the stock cat numbers. They said it made more HP with the stock cats by 2whp... I don't really know how that is possible... First impressions, it felt slow. I don;t know if its because its a **** ton quieter and just feels slower or what. I put the TP map on, and it friggin screams now. Its like stupid fast. Is it okay to run the TP tune with the cats on?

Also, i am most definately taking it to another shop to verify dyno results and see if they can take a peak at the tune and see what the deal is with the test pipes not making more power.

Do they have the TP graph, maybe someone else know better than us but these cars see to ALWAYS gain hp without cats, unless they have the graph I call BS on that, they didn't do it. Time to part ways with this shop...
