Does anyone make a bellow for this application?

It works for both means of measuring air MAF and MAF-less.
Actually you disable the MAF to tune so the method is the same for both setups.
i had a question on egr valve any one know if its better to leave it on for gas milage or off looking at the egr valve timing table looks like they put more timing in when its open that makes me think its better to have left on and as for auto tuning i guess it still on after the auto tune set witch if thats how you are going to be driving it i am sure it should be on just didnt know if it was better performance and gas maleage to leave it on thanks
The only thing EGR benefits is emissions.
It is better for performance and mileage to turn it off. Having the EGR on basically dilutes the incoming mixture with spent exhaust gasses making for less efficient combustion.
Of course you would only turn it off for testing purposes right. :nixweiss:
The EGR has at least one performance benefit; by lowering the combustion temperature, it helps reduce knock. So it's a good thing for part throttle acceleration and high load conditions. Also, the EGR system is only in use part of the time. For example, it is disabled during WOT.
I agree with lowering the combustion temperature, for anti knock, but EGR does this by displacing Oxygen molecules. Hence a loss in power either in part throttle or high load conditions. There are far better ways to do this other than using EGR.Quote:

It's true that when the EGR is operation, exhaust gas displaces some O2. But all this really means is that you need a little more throttle angle let the missing O2 in so you can burn the same amount of fuel. Remember, the ECM tries to keep the A/F ratio constant. We're not at WOT so there is more throttle angle available.
This is a clever way to reduce combustion temperature which reduces knock which we all agree is a performance killer. It has no impact on mileage. It's an elegant solution.
