managed to get to dyno in freezing temperature
only managed 1 run - why fuel pump was not supplying enough fuel
210.5 hp with 14:1 AFR , IT was 210 with AFR 13% back in July
2nd run AFR was 15% and 207hp , last run was 192hp with 16% AFR
But the power and torque was up before fueling became lean
below graph shows today (OEM stacks, new plugs, new Sprint Filter and injectors cleaned) versus run in July this year
torque up from 121 to 125 lbft and 5 more hp across low end and mid range another 7hp @7,000
expecting more top end , new fuel pump ordered , so should be back at dyno this week or next
