there not much small stuff left to do. I don't think the throtle spacers do much. I have one but did not notice much difference. even all the stuff you do just won't give you a whole lot. you can put a corvette servo in the trans. Also could put a after market mass air flow sensor in.

 

You can hollow out the cats...but that wont give u much more hp, only other thing i can think of before you get into the motor is headers but they are pretty pricey on newer trucks, oh also there are those plastic throttle body inserts that smooth the air out(made by vararam)..idk if they do much either though

 

Throttle body spacer will not do anything. Look into a black bear custom tune. I hear that is the best mod you could ever do. Way better than any out of the box tune.

 

ok.. ill do some research on all those.. any rough idea on what my truck will run in an 1/8th mile? just curious if anyone has ran either the same truck or something similar

 

http://www.vararam.com/vr3.html This is the link to the throttle body insert i was talking about. Its not a throttle body spacer.

 

does that vararam really work?

 

No it is just another gimmick. If it worked for real every manufacture would make them and put them in at the factory.

 

Cheapest way to make lots of quick power......nitrous

You can get a quick kit with a smaller bottle for under $200. Just dont over-do it and fry your piston rings.

As for a corvette servo thats just a little insurance for your 2-4 band, and you'll have firmer shifts. (assuming you have a 4l60e)
It wont make you go any faster, but it is a really nice mod and every vehicle with a 4l60e should have one. But heres the question, will they cause your sun shell to break faster? A firmer shift will shock the sun shell teeth and their weak as it is. I don't know...

 

how much are the corvette servos?
