My fuel trims are so out of whack right now because its either good fuel trims and wont run right, or runs smoothly but pig rich. Maybe this could help!

Aaron, there is absolutely no doubt in my mind that you would benefit from the high idle mod.

Lol translated.. Yes, I think it would be a very good mod for your truck. Raising the idle is always helpful.

The 6.1 dual coil upgrade really cleans up the top of the engine. Not that it really matters, but all the old wires/coils must wieght 20lbs. I have an dead cylinder from the initial install, but will get that sorted out in the morning. Damn gremlins. I think this maybe considered a must for 03's.

Edit: Got everything sorted out, not finished with the cosmetics, but it's running great. I won't say I can really feel a difference, but this is a good mod in my book.

Scored some 17x9 aluminum wheels. Can you say lite? Sorry I don't have the pictures up. But this is going to give Red a little different look. It is going to be a very busy week for the old girl... with headers this weekend and cam/ springs and wheels next week. And a little bit of additional drop....

Edit: The guy called and the wheel deal is on hold until the end of the month, one wheel has strayed and needs to be retrieved. We will see....

Update: The wheel deal appears to have gone bust, I've heard nothing more from the seller.....

Current wheels.

Screwed is not the right word more like if you want to modify a 03 you are going to be challenged at every step. The newer models have various tuning options that support a wide range of cam shafts, or if you want to really change the intake/exhaust/heads these mods contribute to more tuning huddles. No one offers Forced Induction for the 03 because the tuning problems are more than they wanted to attempt to solve. Not even counting the transmission being untunable. 03's are great little trucks, usually lighter than the newer models, but if you want to play, you have to plan the until package and build it with a single goal in mind. And there of course always work around to some of the basic problems but requires a much higher outlay of money/ effort than the newer trucks. Out of the 3g trucks I would most want a 05 model, but then that would be way too easy a solution. You will find the 03 guys are as unique as their trucks and at the end of the day I would say probably get more gratification from working on their trucks than they would from a newer model. 03's rule!! well sort of....

This is 03 specific information about how I did my o2 sensors on the LT install I just finished. Each collector has a o2 bung and I welded in another on the Y pipe cross over. As you all know 03's came with only one cat and I did two cats, one each coming off my collectors. So I plugged the front o2 sensor into the passenger side collector and my wideband into the driver side collector and then plugged the rear o2 sensor into the Y pipe which is the opposite side the front o2 is plugged into. Needless to say I have no problem with codes and besides the cats are legal and rated 6000# each. So all is good.

Here is a bit of an update, the high idle mod continues to work as I had hoped, which is to hold the idle at about 700 rpm while in gear at a stop. There are no negative side effects from this mod. I am still on plan "A" for the cam install. Everything is ready and all I have to do is actually install the cam and springs. I finally got all the little bits and pieces together and the install is ready. Unfortunately, I have a issue overseas I may have to attend to and i don't know if I want to have the install incomplete and have to walk away without it being finished. I'll give a day or so to see what happens.
