So I took off my Hotshots and put on some gen 3 cattman headers on my 03 max. My VAFC2 was "tuned" (even though the settings didnt hold) when I had my hotshots but is there any need to reset it and tune it again since I got my cattmans? Reason I ask is because the car "feels" the same as it did when I had my HS. I realize headers are nothing drastic but the sound and the pull is exactly the same. So I was wondering if its because the VAFC is on the previous settings and maybe I need to clear those settings and retune?

 

Might as well, assuming you've got a wideband and can do it yourself.

 

nope no wideband...I'll have to go back to the dyno again

 

Is there any reason to think the Gen III Cattman's would produce anymore power than the Hotshots?

 

Answered your own question.
