Yes. People say this all the time but I have yet to see anyone actually dyno their car with a tune only and then with a tune plus CAI. I did. AED custom tuned my Boss with the stock intake and gained a peak of 7 hp on 91 octane. Later I added a Steeda CAI. Shaun revised the tune to account for the larger CAI and I gained another 13 for a total gain of 20 hp, so I gained roughly twice as much from the intake as the tune. Obviously results would have been better with better fuel but there is no denying the stock intake restricts power.

You need to provide more information on your car whether it be a manual or auto etc etc. Also the stock CAI is the best. The tune would make the biggest difference. AED, VMP, LUND, or Steeda would all be good. No one else. And all the big name tuners give free revisions, not just Bama/American Muscle.

My most recent dyno went like this: I first dynoed with the Steeda CAI and AED tune and got 407. With the car sitting on the dyno I then reinstalled the stock CAI and factory tune. The result was 387. Both these results and Shaun's were corrected figures so the changes in weather and altitude were taken into account. The guys at Performance Engineering had no reason to fudge the figures. It was just a dyno day. They weren't selling me anything. And Shaun certainly wouldn't have had any reason to make his tune look weak. Furthermore I measured the relative restriction of the stock and Steeda CAI's with a manometer. At peak torque there is difference 16 inches of water of negative pressure between the two.
