as long as the baseline was done in similar temp it shouldnt make much of a difference really I wouldn’t think…
haha its ok
the dyno has a full onboard weather station and everything is calibrated to SAE standards
I have dyno’d my car in the summer and in the winter and it has always, always read 299whp. Incredibly consistent.
Is it possible for headers to make this much power? i didn’t think so either, but it truly is reality and not some sort of scam
