Go to a hardware store in the plumbing section and buy a rubber end cap. Its looks great and you couldnt see it unless you look at the hose clamp holding it on.

So I just spent 10 minutes reading this post and not one person posted anything about a real world gain in mpg?? Did this help mpg at all?

Did you read the first post?

"Tighten everything up and enjoy better throttle responce, better milage and better upper RPM "pulls"."

That statement says nothing about a real world gain in mpg - it says "better mileage" which mean what? .5 mpg better - 10 mpg better? Anyone actually keep track of what kind of mpg gain this mod netted them?

Everyones results will be different based on driving habits, gears, size of truck and 2 or 4wd.

My '96 gets 20 MPG (all around driving) with just this and exhaust.

I understand that - but for reference what were you getting before you did this mod? For example:
I have average 13.8 mpg over the past 9 months - after I did this mod I am now averaging 14.5. When I added a higher flow muffler my mileage has averaged 15.2....

Something that shows an actual documented improvement instead of a "seat of your pants" estimate. A lot of people spend hundreds or even thousands of dollars chasing small gains in mpg or hp when in reality some of the things they do actually make it worse! I don't mean to sound stupid or anything - I was just curious because it looks like a lot of people have done the mod on here and/or the silencer removal on these Vortec motors. I would think at least one person would have posted up that they had a "1 mpg" increase in or something like that if it was actually working. Anyone?

Never checked the before, but I know for a fact it was'nt as good stock.

I know what you are saying, but for 20 bucks you really have nothing to loose.

my 96 z71 is getting 20 mpg with hard driving and all ive done is take the lid off and a k&n. im slow on progress with the truck

AcrophobicChevy · 12-07-2006, 02:33 AM

i did the MAF grid delete and silencer bypass i kinda like it....helluva ot louder...MPG would go up if i kept my foot out of it

NacIK · 12-07-2006, 02:43 PM

If it does anything it does make it louder.

coondogz71 · 04-02-2007, 04:01 PM

is there a way to block off the vortec box and leave it on there? just block it but leave it on?

diecast92 · 04-07-2007, 02:26 PM

When you put an intake like this on, don't you have to unplug the battery for 30 minutes to reset the ECM so it will notice the higher airflow?

N0DIH · 04-07-2007, 10:27 PM

No, you can just drive. Everytime the PCM goes to a different load cell, as long as learning is enabled, then it will update those cells. All pulling the battery does is reset back to 128 for all cells. It really doesn't matter, just drive normal. Odd driving behavior will cause learning to be turned off or for it to be wrong when you do hit the cells in the normal driving.

LoneStarZ71 · 04-12-2007, 02:35 PM

I just took the plastic box off mine and used two zip ties to hold it in place, and it doesn't look redneck either.
