i have the S&B intake, i was wondering since i now have a tuner should i upgrade it to C&L intake or just get a custom tune for the intake i have now...kinda stumped

i dont really wanna spent the money on some thing i already have but if it will net me some significant gains then i will do it

 

According to Justin at VMP's testing there is no gain from the C&L on naturally aspirated a cars.
Go with a custom tune and a larger maf. You can get more info from his site start here: VMP 05-08 Mustang V6 Custom SCT X-Cal2 or X3 Flasher and VMP Intake

 

I think there's not that much difference in HP between CAIs. Its all in the tune. I think BAMA works on the Predator and can make up a tune for any CAI no problem. Plus your Steeda 91 tune might work just fine with the S&B. I personally think any tune for a CAI will work with any other CAI.
