Wengerd Performance - smaller, less known tuner. But is just as good, if not better than the larger, well known tuners out there. I was previously tuned by Lund, and now tuned by Wengerd Performance, and I am very happy with the car.
I am at 20 weeks. Ordered in July from Lethal Performance. Initial estimate was Nov 13th. Then pushed to Dec 16th. Lethal says they don’t have confirmation that is has shipped. Waiting on update.
Are you referring to launching a manual car? If that is what you are talking about, sounds like you are dumping the clutch, try slipping it a bit and you will not bog the engine as much.
I am not into drag racing, street racing, or anything like that, so I did not even consider the A10. My wife said only p****** drive automatic Mustangs. LOL. I love my 2018 GT PP1 M6.
Have you had the oil changed yet? Do you know if the engine was filled to proper 10 gallon spec? Let us know what they find. Good luck with the buyback.
