My next test is to get the cruise to WOT readings back down into the low to mid 12's (E10% Stoich=12.2). Once I see what the secondary pump adjustment does to the WOT A/F number, I may reduce my secondary HSAB's down from the current .039" to .036" to see if I can "sneak-up" on the low to mid 12's. I decided to go this route instead of changing the secondary jets because I have leaned out the HSAB's as part of my primary tuning, and now I might be able to reduce the secondary HSAB's back down closer to stock (.031").

Would changing the "Secondary" HSAB's be a better choice or should I just go with the secondary jet swap? Note: My current secondary jets are 80's. This is the easy swap but I am not sure that it is the correct swap, mainly because I would be changing out the secondary HSAB's only.

Thanks
