hey guys im new and i got an isspro egt gauge from vulcan and what size hole do i need to drill pre turbo and what size tap.. any help is appreciated as this is my first diesel and i will never own another gasser. p.s. glad to see there is a good group of guys out here that will help when i have ??'s since i am new to dodge and the cumins.

 

You probably have a 1/8" NPT thermocouple, but there are 1/4" NPT ones. If it is 1/8" you will need a size R drill and a 1/8" NPT tap. The 1/4" requires a 7/16" bit and a 1/4" NPT tap. What is the part number on the thermocouple?

 

bpollard1248, welcome to DTR !!!

It seems you missed getting the single most important guage you can have. A fuel pressure guage will likely end up saving you a lot of money. Do a search and a little reading.

 

Welcome to the site. How long did you look for the introductions forum?

 

You need gauges!

Do you know someone that could spare a few??

 

I wish I knew someone that knows somebody!

I need some gauges for the '98 - a couple of them make the 3rd Gen RP gauges look cheap.

 

Isspros are cheap...and the quality is good.

 

I have had experience with all three, and I really like my DiPricols the best. Their wiring harnesses are smaller and easier to route. They look better, IMHO, and they are very high quality. They are a little pricey, and they don't have a large variety of OPTIX series gauges for other needs, like oil pressure, etc.

 

How about some wide-band A/F ratio gauges in 2-1/16"?

 

yea i know it is the most important gauge but im affraid of drilling into a 23000 dollar truck... im gonna give it a go here next week. i usually stay in level 2 or 3 and i am very light on the gogo petal most of the time. i towed a 30ft camper a few weeks ago in level 1 and 2 and i LOVE how this truck pulls i didnt even think it was back there. guys thanks for all the help yall make me feel like family.thnx

 

quick question kind of on the same topic, getting ready to do mine, but the probe i got looks to big to go in the manifold. there autometer.

 

I dont think you read my post very close. I said the most important guage for is a fuel pressure guage. Do you have one? If not, you should seriously consider getting one.

BTW, how long have you ran an EDGE COMP without a Pryometer?

 

Do you mean it looks too long to go in the manifold? Surely it's not too big in diameter.

 

ohh yea i am going to get a fuel press gauge soon..the guy before me had the edge comp on the truck so i dont know but i have had it for 3 months and i have never been above 4 and that was for about 30 sec i didnt want to hurt the motor or trans. i am affraid to get the egt to high so i baby it like crazy...i even tuck this truck in at night.
