TT-FUEL

Stabilizes fuel trims Smoother gear shifts Warranty Safe

TT-Fuel is a small, stand-alone module designed to restore balance to your engine. By increasing fuel pressure in a controlled way, it takes the strain off your engine’s self-correction systems and helps keep everything running smoothly and safely — even under hard acceleration.

What is TT-FUEL?

Piggyback tuners make power by tricking the car into needing more boost. While effective, it often makes gear changes feel less responsive.

Even drivers who aren’t particularly sensitive can feel shifts become slower and less crisp. More experienced drivers notice the car doesn’t pull as cleanly as it should.

The reason: the engine control (short-term fuel trim) is constantly playing catch-up. During shifts, the engine briefly runs lean, causing that dull, sluggish feeling.

TT-Fuel fixes the hesitation that many tuners sacrifice for peak numbers, restoring refinement to your performance car.

Who is it for?

Designed for drivers running JB4, Dinan, RaceChip, or TurboTransformer.

“If your car feels faster but not quite right…”

“If shifts feel soft or inconsistent…”

“If something feels off even though numbers look good…”

That’s the gap TT-Fuel fills. It corrects the side effects of piggyback tuning and restores the confident driving experience your car was meant to deliver.
