Aftermarket intake and maf
Does anybody know if putting a new aftermarket intake setup on my '01 chevy would somehow mess with the mass air flow sensor? I've seen aftermarket sensors in catalogs like summit and stuff so it got me wondering. Thanks.

It will not mess up your MAF. The MAF recognizes the amount of air coming in and adjusts automatically to it. A nice cold air kit will start making it breathe better. I've talked to some pros about a bigger MAF, like the 80mm over the stock 65mm. Bringing in more air can hurt the performance side of things. I am getting my truck dyno'd this week and will find out if it does hurt it. I switched to the 80mm MAF a couple weeks ago.6" BDS Suspension Lift / 3" Body Lift / 38x15.50x20 Dick Cepek FCII on 20x12 Dick Cepek DC-1 (summer set) / 325/80/16 Dick Cepek FCII on 16x8 American Racing Diamond Back (winter set) / Hypertech Power Programmer III / Air Max Spiral Flow Air Intake / / 80mm Granetelli MAF / 80mm BBK Throttle Body / Helix Power Tower Plus Throttle Body Spacer / 2 Turbonators / Edelbrock Shorty Headers / 30 Series Flowmaster / 4.56 gears /

ok, thanks. I want to get dual exhaust before anything else though. Right now The exhaust leaves that cat and converges into one and that's it. We cut the muffler out but dual exhaust, one out each side behind the tires, will look reall good.

I have a K&N FIPK and a Jet MAF. They work well together, but it does occasionally throw a check engine code, stating that the truck is running on a lean mixture. I had to take the MAF out and clean it real good (autozone sells aerosol MAF cleaner/do not touch the filaments!) which took care of the problem temporarily. I called JET and they told me that the oil from your filter builds up on the filament, causing the lean mixture reads, the sensor is thrown off with the oil on the filament.
I do have a Hypertech programmer as well, which may be part of the issue.
