so, at a machine shop it'll cost around 100 bucks to get it done? and about how long will it take for the work to be done?

 

What a waste! <img border="0" alt="[barf]" title="" src="graemlins/gr_barf.gif" />

 

Polishing the Tb and cleaning up the profile of this factory piece decreases the vacuum signal the MAP sensor sees behind the TB. This is turn tricks the computer into thinking it's under a load (low vacuum signal because of porting work) therefore advancing the timing. Advancing the timing at the same RPM before the modification gives you a little more low-mid range torque.

Hope that helps.

that post is over a year old and you give a reply to it???? that's cool i guess thanks.

 

I was just doing some searching for this topic and thought it deserved a good explanation. Sorry

 

Anyone how much the ones are from Jantzer98ss?

 

Hey look Slow it is one of your many personalities. Back in the I lost my wife and kid days huh?

 

lol, I saw this post and thought Slowverado was back to his old ways agian.
Good research TPCRacing! that is interesting that it is more of a MAP signal rather than airflow...

 

I'm glad the search feature is working good but, when I saw this thread I was like.

 

So...this begs the question, is a Janzter TB worth it?
