How long does a typical full build take at Maximum Tuning?

Average project turnaround is 9 business days for a full build and 2.5 business days for a standalone tune. Complex forced-induction packages and restomod EFI conversions are scoped per project and quoted up-front.

Do you build platforms outside the import and JDM scene?

Yes — the shop supports 38 platforms across JDM, euro turbo, domestic V8, diesel tow vehicles and restomod carb-to-EFI conversions, each tuned on our in-house 4WD Dynapack dynamometer.

Can a build be reverted to stock if I sell the car?

We follow an OEM+ build philosophy: no irreversible harness cuts. Full revert-to-stock is typically completed within 4 hours on supported platforms.

How do I request a build quote from the Builds page?

Click 'Request a Custom Build Quote' and provide your vehicle platform (year/make/model), target horsepower or build goal, and preferred timeline. A calibrator replies within one business day with scope and pricing.

“I walked in with a stock Golf R and walked out with a car that pulls like a different engine. The way Maximum Tuning logs every pull and emails the trace file — that’s the difference between a tune and a calibration.”

— Daniel R. · Golf R owner since 2024

30-DAY POWER GUARANTEE

If the dyno numbers don't match the quoted curve, the tune is free.

My EK Civic went in for a stock-replacement K20 swap and came out with a turbo setup I didn't plan on — because they showed me the dyno curves, not a brochure. Two years later it's still the same tune, no knock, no limp. That's a calibrator, not a parts shop.

We run a privateer FL5 Type R in Global Time Attack. Maximum Tuning handles our calibration between events — they show up with data overlays from the previous weekend and a 20-minute turn-around on the dyno. That's how you win classes, not with stickers.
