Well of course the #1 thing you wanna start with to get better gas mileage would be a tune up. Plugs, wires, air filter, o2 sensor, PCV valve, properly inflated tires, good synthetic oil, clean MAF and IAT sensors, make sure all emissions are up to snuff, running something like seafoam through the engine to clear out any carbon build up and just be kind to the gas pedal.

PCV valve might not have to be replaced, but they are cheap anyways. The easiest way to see if they're clean is to shake em, if it rattles, its good. if not, replace.

Your rice/FWI is killing you. Go back to the stock airbox with a drop-in K&N.

Full tuneup, fix the supercharger problems.

Straight pipe exhaust is too. If there'* no back pulse to pull some air into the chamber, you'll be running rich.

Basically, it'* too free-flowing.

A cheap way to help that (not necessarily fix) is to run a pipe between the two...

Wait, you do have all 6 pipes collecting into one, or no?

He still has stock manifolds. He opened the exhaust too much after the downpipe. He knows. I've told him (and I've told him it sounds like **** )

There are alot of issues with this car. The weight of the audio stickers alone is killing his mileage.

I also ran into him at the parts store recently and saw his pink quasi-FWI made with something like the plastick dryer vent hose. I told him if he didn't take that off his car, I'd take a pic of it and post it.

The heat it'* soaking in, and the restriction it'* giving him is killing both performance and mileage.

Two 10mm bolts hold a square cover on the supercharger.

Or at Autozone. You'll find a PCV at both places. Go to Conifer, cross 99, turn left on 9th. Go about 6 or 7 blocks, Autozone is on the right.



Honk when you go by.
