I'll be getting the OFT shortly. I have an AEM intake and a Spec-D exhaust. I'm curious as to which tune would be the ideal one to use. One consideration, the AEM intake has an extra sensor included with it, so it adjusts things on the intake side by itself (Or so it claims).
Will I still need a tune for the intake, or just something with the exhaust?

Depends on which header you're using. Stock header stage 1 tunes, equal length headers use stage 2 EL tunes, and unequal length headers use stage 2 UEL tunes. For the intake I recommend checking for a MAF scale that's already been done for the AEM without adapter. All the adapter does is compensate for the change in MAF scale. Once you have the OFT you can scale the MAF yourself. Seriously, you won't get the most responsive, quick, and quiet power gains without scaling the MAF as close to 0% STFT/LTFT as you can get it. No manufactured option can come as close as doing it yourself. If you doubt me, just hook up your OFT, select diagnostics, your car, and watch your STFT and LTFT numbers. Positive numbers are too lean, and negative numbers are too rich. Too much either way costs you power and mileage. Anything over 5 positive or negative is worth fixing.
