diesel freaks- any comments

I would assume It's the same as www.performanceharness.com They sell the same thing or build your own! Search caterpillar power harness on this board for lots of info

i tried them on my c-13 they make a reliable product didnt see a real big fuel economy increase but did gain in power,i had both products.

 

Ran one trip with the harness on stock 550 c15 boost pressure went up about 10lbs and the gauge always reads that it's getting boost even going down hill definitely better throttle and quicker response as far as fuel goes to soon to know if you floor it you will get black smoke if you are gentle with the pedal you won't get any

 

A boost sensor mod does nothing for overall performance, you will have slightly better low end response but once turbos make boost it is useless.

Fuel temp gains are seasonal, doesn't work when the fuel warms up.

 

I have them both, don't do it for fuel economy, a little better response and the boost wire, I have the one with the switch so I can use it when and how I wanted, and control the smoke with it, expensive but reliable so far it's been about 2 years and still working good.

I probably feel the fuel wire hp better than most because I have a very efficient fuel cooler, but the best performance it's still in the morning when the fuel is as cold as it can be.

 

What is the big deal with the thick black smoke out of the stacks? Seems silly to waste fuel on something so trivial.

 

Any info on that cooler, link or brand?

 

lets see if this works, https://www.aliexpress.com/item/Tan...1365293223.html?spm=2114.40010308.4.65.wCxpYb

I didn't buy it from this guys but is the same cooler, since I got a totally different radiator I had to re arrange the cooler, so it wasn't cooling like it did before that, then I cut some of the bumper and is a little better, but I'm going to order a rectangular one much longer and than order a custom bumper to fit the new cooler and that should make me a happy camper again, I saw a difference of 30 to 40 degree from the original 18 year old depleted one and that's why I want the bigger one with the new bumper, South Florida is very hot during the summer.
