Frequently Asked Questions
Got questions? We’ve got answers.
How long does the tune take?
A Stage 1 tune typically takes 24 hours including dyno runs. Stage 2 tunes may take longer depending on hardware configuration.
Do you need the car on the dyno?
Will it smoke?
Can you tune specifically for towing?
Absolutely. We offer dedicated tow tunes that prioritise low-end torque, safe EGTs, and optimal power delivery for loaded conditions.
Is the tune reversible to stock?
What if my car has existing issues?
We perform a health check before tuning. If we find issues, we’ll advise you before proceeding. We won’t tune a vehicle with underlying problems.
Is a dyno tune included?
All vehicle tuning files are calibrated on our All-Wheel-Drive chassis dyno, so all our tunes are dyno-tuned.
What maintenance schedule should I follow after tuning?
We recommend engine servicing every 10,000 km and transmission servicing every 50,000 km.
Do you offer stage packages for the Colorado?
Yes, we offer Stage 1 (ECU only), Stage 2 (ECU + exhaust), and Stage 3 (full bolt-on) packages.
