I figured I would start a thread on the problem I seem to be having with my Z. I had the car tuned about a year and a half ago and everything seemed okay but the past couple of months the car seems to be back firing/popping a lot on downshifts (sounds sick but don't recall it ever doing it) and I have really bad throttle lag once I start driving the car for a while. A few of my friends and my local shop think there is something wrong with the tune so its going in tomorrow for a re-tune. I will keep you guys posted but was wondering if anyone has had there car re-tuned due to problems like this.

P.S The shop who is doing re-tune is not the shop he did the original tune.
