my car was road tuned by al a couple of months ago.. car made 314/296 at 22psi on a mustang dyno. Since the last tune I have added Megan Exhaust manifold,ebay o2 housing and an Apexi Cone Filter w/MAF adaptor(previously had a K&N drop in)...

Would these amount of mods warrant a retune the car dirves great has no idiling or sputtering issues whatsoever after installing the filter. Thanks for any advise Al is coming back to town saturday so just tryin to figure it out before then.
PS> All mods are in my sig
The car also ran 3 tenths faster and trapped 2-3 mph higher at the track since the addition of these mods

 

Retune.

 

You always have to get retuned for an intake - everyone knows that, right?

As for the manifold and o2, if you want to get the most gains out of them, you need a retune, too, but they're not like intakes where the AFRs get thrown off. YOu had no need for the intake and still have no need for it. You should remove it until you get tuned for it - there's no reason to have it on the until such time.

 

ok well AL will be here Saturday so im not gonna pull it off for a day...

And the car runs perfect with it on...

 

Famous last words.

 

i would drop cams in there and then get tuned for now i would just monitor the car with a datalogger

 

retune

 

of....

 

I agree with Warrtalon. The best move would be to sell the intake or wait until you've done more before you spend another 4-500 dollars to retune. You could get a mail in cheaper but chances are you will end up with less than what you started with.
