Got a part question, install question, or order question? Start here.
Before you call
Have these ready — it makes the call faster:
- Your order number (in your confirmation email).
- Year, make, model, engine, and trim of your truck.
- Photos if it's an install or fitment question.
Common questions
Will it fit my truck?
Check the fitment notes on the product page. If you're not sure, email us with year/engine and we'll confirm before you buy.
When will my order ship?
In-stock items ship in 1–2 business days. Care packages and large kits, 2–5 days. Tracking emails when the label prints.
I need install help.
Most care packages include written instructions. For specific install questions, call (512) 779-0607 and we'll walk you through it.
Tuner won't connect / programming issue?
This is almost always a USB driver or laptop issue. Try a different laptop and a known-good USB cable first, then call us.
