Thanks, He sent it. I also sent the package via UPS. Your dad has all the tracking information.

Thanks

 

thanks. I'll let you know when it gets here and everything is cool.

 

I got it. I installed it. I Really felt it.
My girlfriend said it sounded louder too. It is much smoother and faster off the line. Thanks!!!

 

Your Welcome! I'm glad you liked it and could use it.

Have fun

 

I guess i don't see how freeing up the intake or exhaust is going to lean up the mixture. If you have more air being consumed, more fuel is going to be added. Additional air is monitored by the MAF, which would richen the mixture to match the a/f table. So if the a/f table is modified with a programmer, the fuel mixture should stay the same, right? Or am i missing something?

 

The part that your missing is that it's not a perfect world and modded MAFs (home port, MAF ends, and Granitellis it seems) lie to the computer so that the car will run a little leaner. That's where the power comes from.
Now if you've got a MAF that isn't reporting the correct numbers to the computer, then put in a power program that tries to squeak out every ounce of timing available and you get detonation/knock retard.
If an aftermarket MAF reports the correct amount of air flow to the computer then your theory will work. But in most cases that doesn't happen.

 

Yes, i do see your point with the MAF. But headers or cat back? That sould not change the a/f ratio. Nothing is being lied to, right?

 

The only way that headers mess with the computers natural ability to keep the motor in tune is that all of the formulas and tables in there are based on the maximum exhaust velocity of the stock system. And it has no way to tell that the velocity is much higher than the stock capabilities. It just tries to maintain the air fuel ratio based on those constants which are now wrong. It can tell the flow of total air thru the motor by the maf readings but the scavenging of the cylinders is different.

I hope that I explained it well enough to understand.
