Do yourself a favor.....Unplug the tors and plug it into itself to bypass, the tors is a built in factory bug that needs to go away. It's the 2 pin plug on the R side on top/back side of carbs if I remember right.

Ray, I read this a little too late. I allready have the SC installed and am going to run it this afternoon here at the house. I have an wideband A/F Guage and O2 sensor so I should be fine as long as I'm between 12 and 14. I am running it in the low boost pully configuration with 91 prem. plus a gallon of 100 LL for insurance pruposes. I'll let you all know if there's still a miss.

The miss is gone 
But I'm running a little lean at 3117" elevation. (17-18 at idle). I don't know if this is due to the red springs or not. MPI recommends the stock ones (can't find them ordered new ones). I'll see if the stiffer springs change this at idle. If not I'll adjust the air screws. I ran the sled with the choke on 1/4 to bring the A/F ratio to the fat side. of Stoich at idle and gave 'er hell. I'll also have to see how much the elevation change to where I normally ride effects the A/F ratio. I normally ride at 6500-10,000+ elevations.

Take out the red springs and go with the stock ones. The red ones will give you fits.
At idle it takes a LONG time for the A/F gauge to work right. Even if it is heated. Mine typically will not read right unless I take it for a quick spin first.

I did take it for a "quick spin"
about a mile to be exact. It folded my bars down into my lap the first hundred feet though :twisted: . I think once the stock springs get her from MPI, I'll adjust it for a little less to the lean side on the idle if it still is. I'm nailing the half throttle and WFO (mid low to mid 13s on A/F at mid and high 13s to low 14s on WFO). Should be good once I get the low lean taken care of. Here's my pic taken during Idle this is with the choke at 1/4". As you can see the O2 should have been plenty warm (water temp 146.3 F). Oh by the way did I mention Boosted
