Do you feel a big difference? I am considering a bit of tweaking but I am still running the stock intercooler and stock exaust with 2 silencers...

Damn Randy! You still running around with no tweaks on your motor? I'm guessing your waiting for your motor to get broken in a little. The difference between a stock motor and a tweaked one is night and day. From suck to blow, so to speak. You can run it with stock exaust and stock intercooler, all you have to do is get an EGT guage and back off the trottle when you hit 1250 or so. Swing by and I will do the tweaks for you. Your fuel guage is going out tomarrow am, fyi.

LOL.. Suck to blow huh.. I def. have to do some adjusting. Dave, is that what you did above? How much did you change your settings? One thing I am going to do in the spring is have a custom exaust done with just 1 free flow muffler to get through inspection. Im sure that will also help instead of the 2 silencers I have now. That has to be quite restricting.

Yeah, I did want to break it in a bit. I still only have 3800 miles on it and my only problem is a leaky oil pan which I will fix at my next oil change. THe EGT guage is next. What did yours heat up to prior to the tweaking?

Oh and Davd M.... the doc file you put up .. the pics are not working.. What gives.

thanks for this thread...

from the bottom of my heart, thank you.

I'm running a bone-stock factory 300 tdi in mine and I need to make these mods in the worst way. My old 90 had undergone a rebuild with new heads after an oil cooler mishap and was unbelievably fast. And now my new truck is slow as Christmas. It's HORRIBLE pulling out in traffic...like taking your life in your own hands. (I'm in Florida, and people here drive like assholes) But, once it gets up to speed, as you Tdi guys know, it's awesome. Smoother and quieter than the 3.9 ever was. But from a dead start..."suck" isn't even the word I'd use to describe it. Unless you insert the F word there in front of it...then maybe.

Anyway, where can I get these mods done? A diesel shop? Will they know what to do? I'm very hesitant to try and tackle this project myself. Honestly, there are tons of things that I did myself to the 90, but the diesel is a different animal. Am I making too big a deal out of it? Or is it pretty straight forward? Everything I've researched begins with tons of warnings and disclaimers...you've seent them..."This will void your warranty", "If done incorrectly this will ruin your engine" blah, blah, blah...Also, I don't currently have A/C, but am planning on putting one in this Spring. If that makes any difference.

I heard that larger hoses on the stock intercooler and huge exhaust pipes go a long way to improving performance without having to tweak anything else. How true is that? Keep this thread alive...

Hey Buckon, you seem to have a lot of answers. You wanna make a trip to Tampa? It's really nice this time of year.

Forgive me for asking something so basic but is the Yahoo! group as easy to find as searching for 'tdi'? I don't frequent the Yahoo! forums. (Who needs to when you've got d-90.com? )

It's really not difficult to do here's the shorter version, took me about an hour including taking the photos.
What ratio transfer box are you running on your truck?

Here's the link to the thread about fuel pump 'tuning'
http://www.d-90.com/forum/showthread...8&page=3&pp=15
took some while to track down as it was hidden in another thread.
It's reply no. 35

It's a noticable difference I can now run a 1.222:1 transfer box with 238/85s and still have acceleration.

I removed the really big exhaust box at the back of the system, it didn't seem to be as "straight through" as the other two, don't know if it made any difference, the noise level didn't really change.
I've never really worried about the exhaust gas temperatures after the first couple of months ( watch, the engine will melt now ) I think a bigger bore straight through exhaust might make a difference, the main improvement was the fuel pump tweeks, made the whole truck much better to drive

I'm now at 2 1/2 turns shorter on the waste gate rod on the turbo.
My mates got brave, asked me to tweek their pumps like I'd done to mine... well I couldn't have their trucks exactly the same as mine could I.

Boost gauge should go in the inlet manifold to measure what the engine actually "sees" and the EGT should go into the exhaust manifold or better still on the head to actually see the temperature as close to the exhaust valves as possible.

Anybody have a good vendor (preferably stateside) for an EGT gauge and sensor?

egauges.com, and I think most on this forum will agree.

Another option. I've been pleased with theirs.

I use these guys EGT & Boost gauges in 2 of my diesel vehicles. The EGT probe needs to be a minimum of 2.5", they also sell gauge housings.
