Great info. I have to read more. What do you think about doing alot of highway towing with a SC?

What brand of AFR gauge is good?

 

Adding the supercharger is a perfect solution for those that are towing. The low end torque is great. I'm making around 200ft-lb torque at only 1800 rpm, it's just like driving around with a bigger motor.

Fuel economy goes to $#@^!. If I baby it for a whole tank, which I've done once just to see, I can still get about 320 miles per tank (about 17-18mpg). That's literally idling around town, which you can do easily and still stick with traffic. But if I play around in open loop I'll get as low as 13mpg. I average about 275 miles per tank now. Since then I've added a 2.5" catback with a straight through Magnaflow, and it's definitely helped with fuel economy if I cruise.
