Pardon my ignorance, Boos is new to me as I have usually been more of a nitrous guy.
I have a whipple on my 4.8 and have been very happy with the results. My main goal was to get the little 4.8 to tow better, which is why I jumped on the whipple. (Got a great deal on it)
It was tuned at 6 psi on the dyno and made good power on a conservative tune.
Today, on my way to work, I jumped on the gas some. (35 degrees outside) Truck pulled really hard. The boost gauge showed 8 pounds.
Is it possble to se this much change due to the cold temps?
For the whipple, which is non intercooled, does the cold weather really helps its performance that much, or am I amagining things?

 

Yep thats normal in colder temps. You just have to be carefull its not lean from the colder temps and more boost.

 

Matt said his Yukon felt fast this morning

 

Oh yeah!! Now that the temps are in the 50*'s here I can feel a HUGE difference in power...

 

yup,simply put you're starting with colder denser air ot start and compressing it just as much so you'll see more of a return.

boost vehicles love cold weather power-wise, and aren't the happiest in heat and humidity (which for me is heavy towing season, between the 24 ft car hauler or the 33 ft cigarette boat)
