WHat idle do u run ur streetport at? Mine runs usually at 1000... But after polishing the trottle body and the manifolds it seems to surge so right now I have it set at 1300... IS this way to much? ill try to take it down to 1100 tomorrow and see if it surges again.

 

mine idles a little high at around 750-800, but nothing like 1000.

Now when it was first set up and being broken in, it was running at around 1000... but thats been tuned down.

 

Mine idled at 1100 rpm after break-in.

 

1500 during break-in and I've ran anything between 800 and 950 since then. It idles perfect at 800 (this is with no 6pi system and combined 2nd/aux port so its open all the time too), but later I was playing with timing and advancing it and with advanced timing the idle gets lumpier at 800, so I bumped it up to 900/950 and it was smoother there.

 

Mine idled perfectly right at 750, rock solid. I had a pretty small Pineapple street port.
