Got my car tuned 2days ago now the manifold cracked so i will be changing it out to a different style one. will i need a retune or will i get away with it?

 

ssautochrome to maybe a ram-horm. or maybe even a log style. whatever i can get a deal on. so what if it's about the same spool time and same lbs of boost. i won't need a retune will I?

 

if u go from log to ram horn or any type of tubular manifold u will need retune, AF is going to be off, just like i had to, went from log to ram horn

I just retuned a ssautochrome to a full-race manifold. It would about a full point off on the a/f. Retune it.

you need to take into consideration how efficient the setup was before, to how efficient the setup will be w/ the new setup.


if its a mellow setup, chances are it wont change much.

if its wild, then yes, it can.


no matter what, i would atleast toss a wideband on the car and see for yourself.
