Cold weather equals more power

[Nine8Six]

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 :/

Both the turbo cars and supercharged cars I've had the difference was big. In the last 12 months we had a huge range in temperatures of low of 19 and a high of 116. The difference with with these difference were in many cases huge. In my three months with the Box the range has 40 to 95. I just came back from a drive and I again stand by the feeling that there is definitely extra power at the top end.
