Does a CAI really improve engine performance ?

Ah I see. We just noticed a slight dip in the great MPG's we were getting after the addition of the intake. must be the ECU compensating like you said. I think if i went on a long hwy drive itd still be higher than befoe. Oh well. I'll have my BBP TUNE soon.

It still DOES stay in v4 longer however.

It got down to 58 Degrees here in CLT today.

My truck seemed to stay in V4 much longer, denser air?
