Isuzu D-Max stage 1 remap from Haverhill. 2.4 seconds faster in our Dragy test is a respectable improvement for a safe tune.

We didn’t dyno test this one, but the estimated gains are around 30bhp and 60Nm.

BMW 320i custom stage 1 remap from London.

Big apology to the customer for this job taking longer than expected, I’ll cover why in a future post.

This is a rare 6-speed manual xDrive, so clutch slip is a consideration.

Settles on 274bhp and 413Nm. Mega gains.

BMW 120i stage 1 remap with gearbox map from St Neots. These results are from a ready-made remap, not custom tuned. I would expect another 20-30bhp could be made, depending on how well the OPF is flowing.

Customer feedback following a stage 1 remap on this Audi TT.

Most remappers wouldn’t know this car had an issue, as it feels much improved. However, our thorough testing process found a lack of top end power and a probable cause. We spent extra (unpaid) time on this job to help the customer with next steps.

Most places just flash and dash…

Stage 2 remap on this BMW 320d. The highlight is the power curve, very strong early on and into the mid range - this is the biggest difference vs a stage 1 remap. Peak figures are limited by the OEM intercooler and intake temps of 45C. Better results would have been seen if tested on a cool day. Customer advised on upgraded intercooler options.

Let’s wait for the comments….crap tune, mine made blah blah blah 🤣

Audi TT 2.0 TSI stage 1 remap from Haverhill.

This one had a fault code for the N80 (evap purge) valve. It dyno’d a bit flat a the top end. I advised the owner the replace the valve, as it’s most likely holding back power due to increased emissions detected.

Still great delta gains for a 160k mile car!
