Notes:

• BPE recommends electric fans that produce 3000 cfm or more, for engines that are 400cid or less. Engines that are over 400cid BPE recommends 4000cfm or more.
• Please note, It is not necessary to run the Holley setup wizard, as this will erase the existing calibration loaded by BluePrint Engines. The ecu is fully unlocked and tunable for further adjustments once installed in customer vehicle.
• BluePrint Engines Recommends Air Intake Kit BPPLS01013 to ensure correct MAF calculations and Dyno calibration are maintained with the above ECU / tuning.
