My 986 gets a 2-season re-mapping! The MAF also has it's little POT as well.... required by my tuner here to get the car exactly where it needs to be. He is giving a little
more air/less gas during hot summer months and LOTs of
more gas/more air during cold winter months
+562whp
April (hot air tune)
Sept (cold air tune)
Average the same +power all year long. Can't stand the sluggish that this motor suffers during hot summer days.... feels as if the manufacturer A/F curves is preset to perform in northern regions only :/
