Customer stories
Real maps, real road tests, real results. Here's what our customers said after their tuning session.
"Absolutely buzzing with the Stage 2 remap. Came to my house on a Saturday morning, set up on the driveway and had the car singing in under two hours. Pulls so much harder mid-range and the throttle response is night and day. Proper professional outfit."
"Booked a Stage 1 for fuel economy and ended up with a car that feels brand new. MPG is up by nearly 8 on my motorway commute and overtakes are effortless now. Honest, friendly and explained everything before touching the ECU."
"Been to two other tuners before BAGS and the difference is huge. Custom map on the dyno, datalogged road test after, sent me the before and after sheets the same evening. Map updates already arrived once for the colder weather."
"Use the van every day for work so I couldn't drop it off anywhere. They came to the depot during my lunch break, sorted the eco map and DPF and I was back on jobs by 3pm. Fuel bill has dropped noticeably already."
"Was nervous about tuning a newer AMG but they walked me through every step, showed me the original files were backed up and the gearbox tune transformed it. Shifts are crisper and the pops on lift-off are exactly what I wanted."
"Best money I've spent on the car. Booking was easy, deposit secured the slot, and they turned up exactly on time. Genuine before/after dyno graphs handed over and the car feels properly sorted now. Cannot recommend enough."
