I have a ramhorn turbo manifold, if I change it to anoter ram horn turbo manifold but and Ac friendly one do I need a new tune? I was looking it up but everyones topic is changing different style manifolds. Obviously that needs a new tune but if I keep the same style do I need a new tune?

Thanks in advance!

unless the tubes are changing size/length it shouldnt be necessary since you arent really changing the dynamics of the air entering the turbine

yes go reverify the tune man its always better safe than sorry

Yeah It's dyno tuned but I think I'll street tune it to see if it's necessary after I switch manifolds. I think it'll be fine without tune like SARswimmer said but your right San better safe than sorry!

length isnt the only differance here it would be the inside diameter of the tubes as well creating more aiflow

personally the 45 dollars or so to throw it on the rollers would be what ide do
