I'll be reporting a comparison to the Predator I run now and will elaborate on gas mileage in detail as well. I don't see anything like that so I'll post my findings there.
I also will be reporting on his PCM electric fan control harness. I like the idea of the PCM knowing exactly what the coolant temp is. I have Flex-a-Lite 292s'. There are no variable speeds, it runs 1 fan full speed when needed and the other when the AC Comp clutches in.
I have a 2003 Z71 Silverado Extended Cab - 5.3, Locking 3.73 gears, E-fans, K&N in OE box, and a SS Silverado cat back, true duals in and the big single out.

I should be reporting my first impressions by mid next week. The MPG report will follow about 2 weeks after.

 

due a home brew intake, that should help some and is pretty cheap. I would like to here this info.

 

what is this harness you are talking about. how did you wire your fans into the truck and get it controlled off the pcm. i am very interested!!!

 

what was the cost for the harness?

 

Cost - $59.00. I havn't received it yet but it ties in the pcm harness in an available pin socket if I heard him right. Next week I'll have pics.

 

did you buy it from nelson?

 

You will like it better than the Predator, I do

 

He says through testing in hot climates one fan is plenty without the AC compressor running.
We will see.

 

You'll love the tune. Its the best thing I've done to my truck.

 

You got the Nelson 93 Tune ?
do you know the dyno for that?
My truck is stock and she hasent seen below 93 yet and I want to put it to use
P.S. can you see my pic in my Signature?
