I talked with my dealer prior to buying the FP tune from Steeda. They agreed to install it at no charge. The service manager said it would not impact my warranty. I have a good relationship with my dealer. They sell and maintain a lot of the FP vehicles. The SM said they have installed the FP tunes on other vehicles, but my car would be the first ST. I think they were curious the outcome.
It was installed today, with no issues. I had already installed the computer software to update the programmer, backed up the stock tune and all they had to do was connect the programmer - press send, give me a $0 invoice indicating they installed it. It was trouble free.
My primary consideration was with shift improvement. The shifting is good, throttle more responsive and noticeably improved low-end torque.
I'm satisfied.
