Had some fun with the dyno, been needing a re-tune for boost increase (30PSI) and change of fuel to VP C-16 (117 octane).
The truck was having problems going lean at the top end. After a few pulls, Buschur was scratching his head until he looked at the injector duty cycle, 104%, so the old 880CC injectors were replaced with 1200CC units, duty cycle down to 64% AFR much more consistent.
The truck is still having a problem above 6500RPM, put in a new set of Iridium Plugs gapped at.018, better, but still something there.
Theory is the boost is blowing out the spark at high RPM. headed out to the junkyard for a new coil this weekend. We'll see what happens over the July 4th weekend.
In this state the truck made 335 HP and 312 ft/lbs Torque, that's Mustang Dyno Numbers, not DynoJet.
