I ran it like that for years with out issue, at this altitude I think I can get away with a little leaner tune. The new tunes for the JLT are around 11.5-11.8 AFR on my gauge (both Brenspeed and JDM). When I first got the new tunes for the JLT they were even fatter than they are now. I had to lean them out a bit working with JDM and Brenspeed via data logging to dial it in. I'll be changing out the stock cams for some Ford Racing Hot Rod cams and will be getting new tunes for them. I'll drop down from the 3.0 pulley to the 3.2 possibly back to a 3.4 depending on how it performs. My goal is to drop the boost down a little and get to similar HP numbers with the cams.
