I'm going to dyno my car and tune my SAFC today at 6pm. The dyno said they can stick a probe up my exhaust without welding it in and get a A/F reading. Is this true? I've always heard of people getting something bungwelded so the probe could go in the DP. I want my reading to be as accurate as possible. What should I do? Also, any tips on tuning the SAFC are wanted also. I already have all the points set, and know how to add and take away fuel, anything else I should know?
