View Full Version : New member, stupid question

06-16-2008, 03:25 PM
Hello to all. I'll get right to the point. After searching the existing threads for an answer and not finding one to suffice I'll drop it here. The patient: a stock 2003 88" bagger with a S/E AC. Installing a SuperMeg 2-1. How many discs to start (instructions say 20) and should I use the end cover's "cap"? Also if the mufller is "closed" how do you use a EGA probe for an A/F reading? Can you run the end "open" with discs and have the access necessary for a EGA probe? Enquiring minds want to know. THANKS! TK.

Start tuning with 16-18 discs with the closed end-cap. Check with your tuner to see if they already have an end-cap with a hole drilled in it. If not have them drill a hole in it (large enough for the probe) and order a replacement from Summit Racing (P/N 406-3046).
