I have been thinking lately of how long i should keep the 4lb on my truck for long term durability. I will have had my truck for two years this coming december. I put a 2lb and chip on it after about 1 month of owning then last summer got a 4lb instead of the 2lb. I have put 15,000 miles over the period of two years and plan on putting about 8,000 miles a year on it. I have it paid for and plan on keeping it for a long time so i guess im torn on what is the point where i should go back to the 2lb or even stock. I dont plan on putting a built motor or transmision in any time soon either.

 

Stick with the 4LB Racer 2

You know what will happen if you tune it down.
There's no going back in my opinion.
Not because of any other reason but once you have that Performance, Power, and Boost, you would not be satisfied with less. (at least I wouldn't)

I go through major withdrawels when ever I sell a Performance Car and have to drive something less powerful. You end up beating it to death, and sometimes even hurting it.

Of course this is just my opinion
