I heard that z1 isn’t the best to go for a tune but what’s wrong with the intakes?
The intakes are fine and so is their tune IF you can get the tune done on location at their store. I definitely DO NOT recommend a remote tune from them. I spent months trying to get that damn tune sorted because their tuner, Jon, NEVER returns calls or emails. You will have to call 5-10 times over the course of a few days just to get him on the phone once to discuss the many issues with your original tune. Then you will need to do the same thing over and over to get the tune sorted for every single data log you do. Expect to go through that process 15-20 times over the course of 3-4 months. It is maddening!
