I was referring to YOUR exhaust, have you thought about installing duals? I've already got dual 2.25" exhaust w/ cats and glasspacks on mine. Changing the modulator valve is a matter of me being lazy, its been like this since I bought it in late summer/early fall of last year.

Sorry about that.
I'm not thinking about duallies. I have a FULL 2-1/2" exhaust. Every turn is made from a stainless steel elbow. Absolutely zero squished bends or turns. This should be more than sufficient and I believe better for low end torque.

I took out about 1-1/2" off the rear lifting blocks and now have no rake. I think it looks alot better. Doesn't look like a 4x4 wannabe anymore.

According to the diameter (.826") of the springs, they were the heavy duty Moog's for a big block truck. I had ordered regular duty springs, but these were in the box and I didn't know. I just cut 1 coil off and took out 1-1/2" off the lift blocks.

Front end alignment tomorrow.

I liked it at first, but it didn't grow on me. Don't know why......

Dyno

Dyno results: ( at the wheels)

The blue line is the first pull. The air/fuel looks like it drops to 10:1 but the guy says its lower as that's where the computer flat lines.

The red line is the second pull with the air filter hose disconnected. It picked up 22 HP and 20 Ft/LBS of torque. The air/fuel ratio came up also but not to where it should be.The guy says I should install headers and the ratio should come up some more.

That looks like one reason for such poor fuel economy.
