Question for ya guys..i have just a few mods done to my truck nothing huge but i was wonderin what you guys think i should do next...so far i got the k&n, a throttle body spacer(i know most of you guys don't like them but it was on the truck when i got it)then i got MAC headers, two high flow cats out through Flowtech mufflers 2 1/2 inch true duals....I see alot of guys mention the Xcal tuner?? What the comparison with the superchip or hypertech?? Im also a 4X4 man so gears would kill me in price??? I am really satisfied with the way these v6 run so im just gonna stick with it and do a few things to it... Anyways some tips on what i should do next would be greatly appreciated.......

 

Without tearing into the engine:

Xcal- Custom tuned for parts on the truck (Others have tunes that are just that, no tuning for parts installed)


ASP underdrive pulley- yours will be cheap make sure you get the belt, and the install bolt.

Is the belt and install bolt on this sight also?

 

Well.... I don't know. The pulley for the 01-02 or (01-06) come with a belt. So if you needed one I'm sure they would have put it in the kit.

 

custom turbocharger! hahaha just messin with you im sure you are on a budget much like me!

electric fans seem to be popular

 

Remove the TB spacer.

 

hahahah, ya you got that right...i wish...

 

Are they really that worthless??Is it robbing power from me by being on??

 

Question for you 4.2trimble...........how does your truck run with your lift and tires...and what bout gas mileage with them gears??

 

And is it robbing power from me??

 

I have seen dyno results that say yea, but I can't find them anywhere.

Welp just by reading that and listening to you guys, im gonna remove the throttle body spacer...thanks!

 

It works for carbs because the air and fuel is mixed be for the cylinder, but on EFI air and fuel is mixed in the cylinder. Any restrictions trying to make swirling air in the upper intake is pointless.


Now when you start messing with the length of intake runners, is when you start messing with power #'s on a EFI.

 

Completely understand!

 

All TB spacers do on our vehicles is make noise. Just like a Flowmaster - sounds nice but can actually kill low end torque.
