Well I have been looking for a truck for about a month now. I considered a Silverado SS, but can't find a used one anywhere in the SouthEast! But last night my best friends Dad approached me with an offer. He offered to sell me his 03 Avalanche North Face Edition, Black/Grey, with 20" GM accessory wheels, and 70k miles for $18000. I have detailed the truck for him a few times and it always looks great. All of his miles are HWY, so the mileage does not concern me. What do you guys think?

Now for the real question:

I intend to tow my GTO with this truck, so whatever I get needs to be somewhat heavy duty. I would really like to add a little power to the truck since I will be towing and Daily Driving the truck. The STS seems like a greta option, but I am wondering how it will agree with towing a 4000lb car on a flat trailer with 2 3500lb axles? Should I just get a Radix SC and call it a day or can I get an STS setup with a few minor upgrades and expect to be ok!? The truck will not tow the trailer for anymore than 250miles at a time, since that is the distance of my drive from my parents house to my house.

Any help would be appreciated! Also which upgrades do guys with teh STS setup get? I won't run more than maybe 7psi, do I need injectors? fuel pump? What???

 

Do the STS with the intercooler option to control IAT's. When towing a load like that, obviously there is more load which means you will be in boost more which means higher IAT's. The intercooler will take care of that for you.
I would go ahead to do injectors to be safe. You will love the torque the STS makes as well as the gas mileage.

 

I had figured the IC would be a good idea!
So an IC and 42# injectors... hopefully that is all I need. Otherwise this is going to get expensive!

 

possibly a pump, but thats only $100.00.
Dont forget a good tune and that should be it.

 

Yeah...the tune is a given! I am actually taking teh GTO in tomorrow for a retune with the new pulley set! Cross your fingers for 600rwhp/510rwtrq on a stock bottom end/head setup with my blower!

 

damn, sounds like a nice car.. My brother actually has an 03 sss but i think he wants to keep it right now, but he is selling his brand new gt67 sts kit if your intersted, we are in the south east so if you are interested let me know.
