Unlock Your Engine's True Potential

"Sent a 335d original over, had the Stage 1 back inside 25 minutes. Flashed straight in with KESS3, no checksum issues, drives lovely. Will keep using."

"Golf R Mk7 with downpipe and intake. Asked for a sensible Stage 2, got back a really clean map — boost is steady, no spikes, lambdas look healthy on the logs."

"Transit Custom 2.0 with a blocked DPF. Off file came back with EGR and flap also disabled as requested. No EML, no limp, customer happy. Pricing is fair too."

"Scania R450, AdBlue tank knackered. Off file done properly — no countdown, no derate, no fault stored. Saved the customer a fortune in DEF parts."

"Used to wait hours with my old supplier. With TBT I usually have the file back inside 30 minutes. Quality is the same or better. Easy switch."

"A4 2.0 TDI with a sticky EGR. Software off + blanking plate, ran the cycles, no codes after a week. Straightforward and well-priced."

"Done about a dozen DPF files this month through TBT. All clean, all first time. Their support replies fast if you need a tweak."

"M2 with downpipe — asked for low-mid focus, that's exactly what came back. AFR target held nicely, no fuel cuts pulling top end."

"Fiesta ST Stage 1 with crackle map. Sounds great, no misfire codes, idle stayed clean. Customer keeps sending mates over."

"Sprinter 2.1 CDI eco file — fleet manager logged a real 9-11% drop in fuel use over the month. Drivability still good, no complaints from drivers."

"Range Rover Sport 5.0 SC. Stage 1 felt straight away — pulls cleaner from low rpm. Polite and quick to answer questions on WhatsApp."

"Volvo FH16 AdBlue off, 20,000+ km later still no warnings or torque cut. Solid file, solid service."

"Built RS3 with hybrid turbo and bigger injectors. Stage 3 came back well-mapped, knock retard stayed near zero on E5. Proper job."

"Discovery 4 3.0 TDV6 with cracked DPF. Off file did exactly what it said, no codes, runs perfect. Fair price, no faff."

"Insignia 2.0 CDTi rough idle and smoking. EGR off via software, plus blank — idle smoothed out, smoke gone. Cheaper than replacing the valve."

"Giulia QV Stage 2 with sport cats. No CEL, no flat spots, gearbox map blends in nicely. Customer over the moon."

"Civic Type R FK8 — added hardcut launch and a pop overrun. Both work properly, no error codes. Turned around in under half an hour."

"First time using TBT, 1.6 HDi 308. Stage 1 added a real ~25bhp on the road, MPG ticked up too. Will be sending more."

"DAF XF 460 AdBlue off file — no fault stored, no countdown, no derate after months in service. Customer saved a 3k+ repair."

"L200 2.4 DI-D with DPF and EGR issues. Combined off file, blanks fitted — runs cool, pulls strong, no warning lights."

"320d F30 with intake — Stage 2 felt smooth from 1500 all the way up. No DTCs, lambda looks normal. Honest pricing too."

"Octavia 1.6 TDI eco file dropped real-world consumption by ~0.8 L/100km on the customer's commute. He came back for the wife's car after."

"535d F10 Stage 1, kept it sensible at ~340-350bhp. Boost stable, no smoke, gearbox handles it fine. Back in around 20 minutes."

"Focus RS Mk3 with downpipe — Stage 2 file held a flat ~400bhp on the rollers. No fuel cuts, no overboost. Clean work."

"Mondeo 2.2 TDCi DPF off, no light, no regen attempts in the logs since. Customer thrilled, fair price."

"Done a few Iveco Daily vans now with AdBlue and DPF off. Every one has been clean — no codes, no derate. Reliable supplier."

"S3 8V Stage 2 — 370-380bhp on the dyno, transitions are smooth, no flat spot mid-range. Map feels properly developed."

"2.0 BlueHDi EGR off after the valve failed. No codes, no limp mode, runs better than before. Quick reply when I asked a question."

"Cupra 290 Stage 1 — power delivery feels OEM-smooth, just stronger. No DSG hesitation, no error codes. Customer delighted."

"M140i with hybrid turbo — Stage 3 file pulled a strong ~500bhp, knock control behaved itself. Worth the money, no question."
