i have added a 58mm tb and ported my intake to match, how much if any hp do you guys think that would have added to my le heads/cam car??? when i dynoed her at 394rwhp this was without the 58mmtb and ported intake. thank you.....brian

 

By "ported intake", I presume you mean "gasket matched", as opposed to "ported"...?

Anyway, did you have your computer program updated for the larger TB?

 

yes gasket matched. and no on the computer program upgraded.

 

well....Im willing to bet you break 400whp..heh

I think you will see a nice gain....but you may lose a little low end grunt

 

i hope i do
