A few months back i did the 10k mod and saw considerable power gains on the dyno. Well that wore off already and i have read that you can use an adjustable resistor from 10-18k. Is there anything wrong with just putting in a 15k resistor instead of the 10k and leaving it like that all the time? Does it need to be adjustable for over 10k where its not up high all the time? Thanks.

The more resistance you use, the less power you make, so if you put a 15k resistor in, you'll have less power.

The less resistance you have (10K in your case) will give you more power but at the expensive of idle quality.

The reason for adjustable resistor mods is so you can have decent idle quality when you turn the resistance up, but more power when you turn it down.

You may want to check out the 18K, offers better power than a 10k and is throttle activated, so most idle quality issues are non-existent.

Yup, as stated, the higher the mod, the LESS the power.

3.9k is about as low as you can go, and even then some trucks choke. You have to play around a little to find what your truck likes.

Wow. Guess i should do my research. I was under the impression from friends that going up in the resistance would make more power. I'd like to try and get a little better power so i guess i'll put in a 6 or 8 k and see what happens. I did a dyno test with the 10k and picked up about 35 hp and 111tq so we'll see what it'll do with a little less resistance than the 10k. I've got EGT etc so i'll keep an eye on them. With no load on the back what would be a good number to watch out for on the EGT ? 800-900? With the 10k and no load behind it its been running about 500 around town/highway. Put a load on it and it has been seeing about 875. Where do i need to stay to be carefull? Thanks

A good number for max EGT is 1200 degrees pre turbo but not for long I tend to get out when I see about 1100 or so. But that is me some people are different.

Garrett (The guys that BUILD our turbo) have stated these trucks can run for DAYS at 1250 degrees PRE turbo temp. You can push 1300-1400 if its only for 10 or 15 seconds of racing, so long as you let the truck cool down before doing it again.

I stick to the manufacturers recomendation of 1250.

These trucks like it hot and sweaty, so when towing a big load, and coming up on a hill, get those EGTs up, and the RPMs up, and you'll fly up that hill.

the more resistance there is the more its like it is not there... think about it that way.

Thanks guys. I put a 7.4k resistor in it now. Feels pretty good and the Egt's only went up about 75 deg. or so. Im going to dyno it monday as soon as i get to work and i'll let everyone know what it does. Im thinking its time for me to build a bigger downpipe and probably intercool it.

Did you ever get it back on the dyno? Also where did you find the 7.4K resistor? All I can find at the local radio shack is the 3.9, 4.7, and 5.6 ones.
