Hello all,

I currently have the Roush CAI installed on my 07 GT with the MVT in and now I am looking at grabbing a SCT tuner and getting a tune for the car for greater gains. I am wondering though if there is a big difference in tuning with the MVT in vs taking it out. My car is pretty much stock other than the intake and some mufflers. If the difference is not that great I would prefer to leave the MVT in just to make it easier if I need to bring the car in for work at the dealer. However if the difference is great I will pull it out and get the tune for that.

Thanks

Dont take that piece off. The only time it would need to be removed is if the cars highly modded.

I have an airaid on my car and i was curious about that too, so i asked Brenspeed about it and they said to leave it on and i also called airaid directly so they said the same thing.

Thanks for the response!! Did you tune the car at the same time you put the CAI in or after? If it was after what kind of gains did you notice with the tune?

Thanks again

I tuned it at the same time i installed the intake, full exhaust and pulleys. But the tune is just a email tune from brenspeed. i still need to get it dyno'ed ... so i wouldnt know the gains i got. But hell with all that stuff i installed i noticed a big difference!

Brenspeed told me the same thing. Leave it in.

If tuned properly for the larger MAF housing it should perform better with it removed. Granted you might not see it unless you add some other supporting mods (heads, cams, headers).

IT would be to unstable never take the venturi out of the intake.

Thanks for the info guys I think that I will just leave it in. Have you guys ever seen any dyno numbers on what to expect from the CAI and tune? I have searched online and can find info for the JLT and a bunch of others, but never the Roush/Airaid with a tune. I would like to run the 91 Octane performance tune from Bama once I get my tuner.

Thanks again!

I picked up 25 RWHP when I RAN the AIRRAID. I now have the Jlt and really have not noticed much in my et if any. I almost miss the Airraid to be honest. It is a very nice and well made cold air intake. I ran the 91 race tune and loved it from Bamma.

What was the reason you switched away from the airaid? I am really looking forward to getting the tuner 25rwhp is a pretty nice gain!!

I was told I could get 10 more RWHP BS . I miss that deep growl from the Airraid also. Oh well. You will be very pleased

I love the sound of this intake!! 4000rpm and above is pretty much the best sound I have ever heard They say you get better gas mileage which is total bs because all I want to do is hear the sound coming from the intake.

:rollgrin: lol I waisted a whole gas tank just because I wanted to hear the roar of the new cold air intake and the GTA Mufflers my first mods.:bigthumbsup

I have the Roush CAI and was only able to remove the venturi once cams were installed and a custom tune loaded. Longtube headers are on order as the next mod.
