great thank you for your input. I will get itune after the holidays.

Thanks for the info. I have been looking at them. I also like that they are from Michigan my home state.
I'm guessing the cai and the tune should really bring the truck to life.
Which would you do first? It is alot of $$$$ for both. Were is the best money spent first.

is a cold air intake worth the money. I plan on getting the i2030 tuner. i have a 2013 gmc 1500 sierra. I've been reading mixed reviews on getting a cai. Some input would be great.
Thank you in advance.
