Really? Have you ever talked to Keith about your issues? Because when I read through your member galley thread you spoke of nothing but how great your car was running on your awdtuning tune. And according to the pictures of your car at the track with your dad (which is awesome btw) your license plate shows a California address? I personally have not looked at your billing to know if your sales tax claims are accurate but I can only assume that if Keith or someone at the shop didn't charge your sales tax in an effort to help you save money then they only did because of an out of state address which would have been verified.
Also, you do realize that we don't charge sales tax on services such as a tune, modifying injectors or labor? Sales tax would only apply on parts and again I'm unclear of if you purchased parts through the shop or not.
Now as for the injectors, Keith has never once made any claims of exactly what they flow. He speaks of a range but if there are ever any problems he does everything he can to prevent or correct any issues. Not sure what happened with these injectors you speak of because it has not ever been brought to our attention that there were issues. But I do notice that your engine is still running and I happen to know from experience that if an injector failed, stock modified or aftermarket, that the car would start running very badly and could lead to engine failure. All of which you don't seem to have.
I am sorry for anything that we have done to make you feel wronged as it is never our intention. We started the shop to help people save money in anyway we can. I personally ran modified stock injectors on my car for a year with no issues and would not recommend the option if we knew of issues. While I will agree that purchased aftermarket injectors is a better option, sometimes funds prevent people from that option and we are just trying to help.
Again I apologize for whatever happened and if there is every anything we can do for you just let us know.
Ps thank you for your service to our country. I have lost family members in the line of duty and have many others that still serve. Your sacrifice is not something that we take lightly. Thank you
