Dyno numbers affected in horrible weather

I just had my 2016 GT Performance Pack tuned by VMP on a mobile DynoJet in the rain and the temp was around 50*. How much does this affect the real numbers? It made 403+ rwhp and 402 rwtq with a Steeda CAI and Ford Racing (Borla) exhaust. I witnessed another 2016 GT (standard) with the same exhaust and a JLT CAI only make 372rwhp and 369rwtq dyno’d in the same conditions ( both 6spd manual)

Cool air creates more horsepower as a rule. The JLT CAI was doing absolutely nothing for the engine as 369 is about right. Apparently your Steeda CAI added some 30 hp which is impressive.

Cold air = more dense air since o2 molecules come closer together so more oxygen in given amount of space.

Hot air= molecules separate which means less oxygen in given space.

Naturally asperated motors are at the mercy of ambient conditions more so than boosted cars.
