Okay, so I have Dave@DDMWorks Stage 1 Turbo. Installed myself with some coaching by Dave 18 months ago.
Started having some backfiring this past weekend. Sent a note to Dave - AND HE ANSWERED WITHIN THE HOUR! Told me to look for a couple things, which I did. Eventually I found the issue (loose nut between the steering wheel and the seat - yeah, I'm an ID-10-Tee) and got it fixed.
But I just want to thank Dave@DDMWorks for his help and quick response. You don't find customer service like that everywhere. Which is why I keep spending my money there.
Thank you Dave!
