I recently brought my car back to stock short of removing the green filter and the 3inch roush exhaust. I was running stage 2 Cobb OTS tune for a good 6 months and would constantly see 24.7 MPG as my commute is pretty much all highway. I figured that removing the tune and intercooler, I should get back into the 26-28 range but I checked this morning and I'm still at 24.7 MPG. This just doesn't seem right to me. I didn't reinstall the shutters and I'm sure that will get me 2-3 MPG but the fact that I'm getting the same exact MPG just doesn't seem right.
Thoughts?
