Default Replace Screen in MAF Sensor

Replace The Screen in your MAF Sensor. This will Solve your Problem! Stop Altering the vehicle. GM Built it to run that way with the screen. Be nice to your car.

when you installed the new intake, did you disconnect the battery and let the pcm power down . if you didnt, the pcm is running on the way the air was going past the MAF before the mods. you should have powered down the pcm and let it relearn itself to the new readings coming in from the IAT and the MAF sensors. anytime you do a mod to a computer controlled car, you must do this. if you dont, it will set a SES untill it goes through a certain number of ignition cycles to relearn the pcm.

I assume this is good, unless something is in danger of being damaged.
Does this situation sound safe to you guys?
Yes, more air availble before the TB will increase your final boost, but remember that the colder and more humid air this time of year can have a big effect on it, too. Running the SC up into the 'danger zone' on the gauge isn't a problem. By the end of Feb, I should be boosting around 12 pounds. Way off the scale.

Default Still no lights- Pulley advice?

A sincere "thank you" to everyone posting their advice and experience.

About 6 weeks and 3500+ miles after reinstalling the MAF screen and disconnecting the battery for a while, I have YET to see either the SES or traction control lights. Thank goodness, my car has run perfectly and powerfully, with great gas mileage to boot!

I now have a little Christmas money to spend and am looking for a SC pulley.
Also, I will soon be looking to make minor-to-medium level upgrades to the exhaust system.
Who and what should I deal with?

Any and all advice on pulleys and exhaust for my SSEi would be greatly appreciated, and thanks in advance........
Randy

This is the best source for the 3.4" pulley. Note their disclaimer about the tranny cooler, intake and exhaust:

Get with Hector at ADTR on the exhuast. Otherwise you'll have to piece a system together like everyone else up until now. SSEi95 was the most recent. There'* some posts in Performance on that.

Since you guys are discussing 4" intakes. I still have the airbox with K&N but i got rid of the front of it and ran the 4" between the fogs. I * that ok for the best power?

Best for power is the 3" mandrel bent tube with a cone type filter on it. Better velocity and laminar flow. Yes, I am describing the ADTR. Hector spent quite a bit of time developing it for us, and put all that knowledge into the production unit.

What you have now is similar to mine (go to my website and see the pics under my hood) and is better than stock, but still not the whole ball of wax. Still room for improvement.

I thought about the ADTR. The prob is that I was thinkin that since the homemade duct is sitting with no air restriction then it would get more cold air then the ADTR. Bec the Hector unit it still entraped in the engine compartment, right or wrong?
