Ok so I just bought a 07 dodge ram 1/2 ton 4.7l and I want to put a turbo on it with a programmer and cold intake and I would also like to change the gear ratio what are y'alls thoughts and also I put led interior light and at night when I'm in it one of the 3 lights stays on how do I fix that?

 

Do a little research. Do you have a bunch of money to throw at this project? Depending on boost level, the 4.7 will need to be beefed up. You will need a custom tune. Transmission will need work to handle the extra power. No sense installing a cold air intake since the intake system will change and nothing off the shelf for a 4.7 will bolt on. As stated, do some research before deciding if this is worth the time and money.

LED's will stay on dimly due to the small amount of power required to turn the, on compared to incandescent.
