Poor MPGs after AFE Intake/ Continue with SRL
About 2 weeks ago I put an AFE Stage II Pro Gaurd. The one with the battery in the air box. Running about 65 mph i would average around 17-18. After putting the intake on I dropped to about 15.5. At that time I was running the canned performance tune on my SCT. I just downloaded Matts SRL tune early this week got 15 in city driving near Chicago. Came home to Indy for the weekend and going 65 I only got 16. Hardly any wind. I did just adjust my tire revs per mile and the rear end setting was set at stock. So I did enter on the 373 one. Help me out if you can. Also I just put on a Sinister Coolant Filter. Wanting to do the Amsoil By pass filter in the next few weeks.
