TT-FUEL
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.
Why Use TT-FUEL?
Piggyback tuners make power by tricking the car into thinking it needs more boost. While that works on paper, it comes with a side effect many drivers notice right away: the car doesn’t feel as smooth or responsive during gear changes.
Even drivers who aren’t particularly sensitive can feel shifts become slower and less crisp. More experienced drivers also notice that the car doesn’t pull as hard or as cleanly as it should. The reason is simple: the engine control (short-term fuel trim) is constantly playing catch-up to keep the mixture safe and balanced.
When you shift gears, the engine briefly stops controlling the fuel mixture (ECU goes open loop). During that moment, the engine runs lean and hesitates ever so slightly before settling back in. That hesitation is what causes the dull, sluggish feeling during shifts.
In short, while many tuners chase peak numbers, they often sacrifice smoothness and drivability — the very things that make a performance car feel truly fast and refined.
How does it work?
Just like a piggyback tuner, the TT-Fuel Kit connects directly to your fuel system. But instead of chasing power numbers, it focuses on fixing what other tuners leave behind.
By stabilizing fuel delivery, TT-Fuel brings your engine back into sync. The result is immediate and noticeable: stronger pulls, cleaner acceleration, and gear shifts that feel sharp and decisive again — the way a performance car should feel.
Who is it for?
TT-Fuel is built for drivers already running a tuner — whether it’s TurboTransformer, JB4, Dinan, RaceChip, or similar systems.
“If your car feels faster but not quite right…”
“If shifts feel soft or inconsistent…”
“If something feels off even though the numbers look good…”
That’s the gap TT-Fuel is designed to fill. It corrects the side effects of piggyback tuning and restores the smooth, confident driving experience your car was meant to deliver.
