Bought a used diesel with an unknown tune? We read what's actually on the computer before you tow, mod, or re-tune it.
Consult fee — ask for current rate; often creditable toward a full tune

A previous owner's tune could be anything — aggressive, half-deleted, mismatched to your current mods, or just undocumented. Towing or adding power on top of an unknown calibration is a gamble. We read what's there first.
Book a consult → we connect via AnyDesk → read your current ECM/TCM calibration → walk through findings live → recommend next steps. Support expectations follow Eastern Time business hours. Local meet-up available around Land O’ Lakes, Lutz, and the greater Tampa Bay area.
If what's on there is safe and matches your goals, we'll tell you to leave it alone. If it needs work, we'll quote a revision or a fresh documented tune — built around your truck's actual current setup.
If you bought a used diesel, you often don't know what's loaded on the ECM/TCM — a previous owner's tune, an unknown delete, or something half-finished. We read it, explain it in plain English, and tell you what's safe before you tow or add power.
Usually a paid AnyDesk screen-share — we connect to your laptop and tuning software, read the current calibration, and walk through what we find live.
Ask on your quote — in many cases it's creditable toward a full tune package if you decide to move forward.
We'll tell you plainly and recommend either reverting to a safer calibration or building a documented tune around your truck's actual mods.
Yes — this is one of the most common requests. Checking what's on the ECM before you commit to a purchase is smart money.
