The DTS Guides

Straight Answers About Tuning.

Every guide here was written from the questions real customers actually ask us — on the phone, at the counter, and through the website. No hype, no fabricated numbers, no jargon walls. Pick your question.

Can We Tune Your Vehicle?

The #1 question, answered in thirty seconds — plus what we tune, by name.

What a Tune Actually Does

The honest first-timer guide: what the ECU controls and what you actually feel.

Installed Parts? The Tune Comes Next

Why intakes, downpipes, turbos, cams, and E85 need a matching calibration.

Hesitation, Misfires & Mystery Codes

Diagnosis first — and a straight answer on whether calibration is the cure.

AFM, DFM, DPF, EGR, DEF — Explained

What these systems do, why they cause complaints, and where we stand.

Tuned to Burn Less

Economy calibration for trucks, fleets, and farms — with BlueOptimize™.

Locked ECU? What That Means

L5P, B58, Hurricane, Elantra N — locked is a speed bump, not a wall.

Pops, Launch Control & Better Shifts

Character and transmission behavior are calibration too.
