I am trying to decide if I should attempt to install the factory Titanium jet kit myself. My father is a good mechanic, but what jet would I use with a Leovince highmount and a BMC or K&N filter??

I want to do it myself but i am worried about not getting the right one.

I just want something for the time being till I can get it dyno tuned.

how did you guys get yours tuned????

 

or can I shim the needles and not get the jet kit quite yet??? I would rather spend the money on something else if I can.

I would just do the leo exhaust no filter and shim the needles.

 

why dont you get your exhaust first and see how it runs?

 

Most of the time you don't need to jet for just exhaust espeacially with the added back pressure from high mounts. The only reason I did mine was the added flow of the k&n filter.

That said most kits have instructions on what to use for what application. Ex. stock exhaust stock filter use these. Free flowing exuast and filter use these.

Sorry let me clarify that with slip-on exhaust, full system would require rejetting.

 

that what I thought but I wanted to make sure.

 

superhawk22 - I have to add this

Because what you wrote is misleading

Stock exhaust systems are restrictive, (they have to meet EPA emission and noise restrictions) They compromise.

They lean out the carbs, to get past the EPA.

Aftermarket exhaust systems (slip ons included) are less restrictive.

This means that you get better gas flow with aftermarket exhaust. Generaly speaking if you put on a aftermarket exhaust and a jet kit, you get better performance, sometimes better gas mileage too!

 

Better performance yes, but the question was is it needed and as I said, with just slip-ons it's not always neccessary.

That's all I was trying to say but yes you are correct.
