Exhaust valve mod and gas

bimmerking818 · 03-16-2015, 05:05 PM

Hey guys so I got my car 3 days ago and I did the valve mod yesterday, and now I see the car eating gas like its nothing haha. So my question is does this mod kill your gas mileage or is it just the car itself? Or is it the way I am driving it? And yes I am keeping it under 5000 rpm.

Thx already guys

Valve opening/closing has no impact on mileage.

Mileage is directly related to the right foot

lol..try keeping it under 2500 rpm for the suggested MPG the car was sold as.

....which is impossible

Valve mod is actually correlated to lower MPG. Your car now sounds better so you really want to push those revs to hear the exhaust

Is exhaust valve mod will void any warranty?

If it triggers a CEL the key records it so possibly depending on how dick your dealer decides they want to be.

Baffles me as to why most people are so keen to fuck with a car that is pretty much perfect out of the box / beyond their driving capabilities as is.

Particularly a hokey mod on a 70K + car. Just leave the car in M2 if you want your valves open
