ok...i also noticed the noise got even worse when i put the msd 6al on...it's louder and it sounds different...btw the noise is there when it plays cd's also...and it was like that before the msd but the msd just made it louder

 

Thanks guys.

The truck ran like a top on the ride home to install the plug wires. Immediately after is when I observed all this stuff. I think it could be part of the cold weather thing, but last night it was aroud 35F, and the truck is DEFINITELY down on power on the highway. It would take it's time to get up and go - like a turbo-lag kind of thing. This really bums me out. If it wasn't for the better gas mileage, I'd probably have already pulled these out. I don't want to give up just yet.

I used dielectric grease on all the connections...

I don't have any radio noise...

The exhaust note is just about back to normal. That's throwing me for a loop.

As for the other SS stuff - Mods for next year here: I want to put in a Comp Cam's 212/218 522/529 114, cutouts (electric?) on the stock exhaust, Yank 2600, lighter rims, and I have a UPD in the mail. I also want to pick up some diagostic software and Edit. I might spray it next-next year.

I haven't really got the truck in any serious snow yet. We had some squalls come through the other day which caused all kinds of problems for the bad Massachusetts drivers, but I never even got a slip... without trying. I think we're looking at a foot or more for the weekend, so I'll have to get back on this one.

 

Just wanted to post and update.

The engine has been moody as anything lately. Some days it runs awesome. Park it for 20 minutes, take it back out, and it's a turd... and vise versa.

I went to swap my stock wires back on. Two of the Taylors let go on me. Both of them left the spark-plug clip still attached to the plug.

It looks like those metal clips were attached too tightly to the inner core of the wire, comprimising it's strength.

Put the stockers back on, and the engine is back to what I'm used to. Kicks down at the drop of a hat. Pulls much more 'freely'. Throws those lazer warnings all the time.

I'll see what Taylor says about this.

 

I hate to tell you this,but it's most definitely your new igintion wires. This is why I get so aggravated at the aftermarket. All wiring is not created equally. These big brand name guys buy wiring in looms from overseas and have their name stamped on it in whatever color is sexy and looks racy. They get cheap on the quality because they know that most people know nothing about it. They can then in turn sell more of their products at a cheaper price to speedshops and merchants and offer them a greater profit margin. I've grown up around racing in someway or another, and alot of the professional teams do use a brand called Magnecor. Magnecor has a paper on their website that will say something close to what I did. I went with Magnecors on my Camaro, because of what I learned from being around racers. I can almost guarantee you what you experienced with those other wires will not even happen with Magnecors. Here's their link:

Okay... digging up this old thread to post a longer term follow up.

Taylor replaced my wires for me. They said they were improperly crimped.

I hastily tossed on the new set last night. Didn't measure any ohms or anything. I figured they'd be coming off again soon.

Nope, the truck runs mint. I got the results I first expected.

The truck pulls much cleaner throughout the entire RPM range, it has a nice healthy tone to it, and it takes much less throttle to get the truck up to speed. I'm REALLY happy.

I actually saw 18.1 mpg on the ride into work this morning. That's in a 5,300lb truck with a 6.0 and AWD. Not too shabby...

 

And no foot in the throttle I bought edit to try and figure out how to get my truck to give reading in gpm.

 

I was taking it easy, but I was in no way "that slow guy". I still pulled a few holeshots at lights.

GPM? Have you bought stock in any oil companies lately?
