I'm so happy that your tune is working out for you!
You'll need to fill out an order form:
Power Hungry Performance - Ordering Info
Based upon our current workload, I'd say that it may take up to 6 weeks for your tune to be rewritten -- so don't install that CAI yet!
(It may not be that long, but I'd rather overestimate than underestimate.) Hold off until the tune is ready, or you may run a risk of running lean.
