There is nothing wrong with a CHIP to retune your truck if you do not want to learn or know how a tuner works OR just don’t want to take the chance of screwing up your existing setup.
A CHIP is quick and easy, unplug the computer, plug in the reprogramming chip and then the computer connection, easy, done and they do work.
BUT… to the point... I agree with Shawn, to criticize someone’s for sale item just because you think you know better is not right and should not be allowed.
A lot of for sale thread have gone to the wayside because of pi$$ poor comments and/or comments that take the classified in a different direction.
If you want to comment on the item that someone is selling then go to the general comment section and start a thread on it, then the site can take action against you for causing trouble on the site.
Sorry for jumping in but the comment thing is something that pi$$es me off.
