[QUOTE="TRBO VNM, post: 11893860, member: 14678"] I am going to go against the majority here. But first I will say getting a retune isn't a bad thing. At a MINIMUM you should have it checked. It will depend on how the car was tuned. This has been discussed in the past, but not sure if you will find the threads because it has been a while from what I recall. There are different ways to tune a car. It can be tuned such that by adding boost you do not have to have a retune. The computer will adjust for the additional boost and add the fuel needed to maintain the a/f. When I had my turbo setup, I could go from 10# to 25# of boost without changing my tune. I just needed to make sure my fuel octane could support the power. So if you have the octane and your fuel system is setup to handle the power, adding boost does not mean you have to retune. But it depends on how it was tuned. So those recommending to find a new tuner, that is incorrect. OP, like I said, getting it at least checked on the dyno or street logging a/f should be a minimum. It doesn't necessarily mean you need a retune. [/QUOTE]
