Default weather vs performance.

I got my truck this summer, it has a non intercooled magna charger w 30lb injectors nelson 93 tune gibson muffler and a drop in k&n.
will this cold weather be like a huge wake up for my truck?
it runs like a dog in the summer heat. let me know guys,
and on a nice cold day how much better could it possibly run?

Perhaps an extra 20-40HP when it's cold like <60 outside.

First morning when it is about 50-55 degrees it will feel like a different truck.

Have you thought about going with meth injection or a small shot of n2o to cool down your intake temps?

Take a look at the Dyno vid in my sig. It shows how Meth added approx 20hp when used with a Whipple. It is proof enough to me that meth makes a difference. My next step is to get some IAT and Knock readings with and without the meth.

your truck is a daily driver? just curious.

btw you lost torque?

More of a garage queen as opposed to a daily driver...although it is 100% dependable. I get between 16 and 19mpg dependent upon how I drive. 50-50 mix city/highway.
Yea, I noticed that too...gained HP and lost torque. I think the torque reading is just the high point, as opposed to the average over any range. After looking over the dyno graph, it appears that tq was up overall, just not as 'peaky' as the first run. HTH.
