Discovery 2 TD5 Monster Tuning Remap

We were pleased to be able to offer a Monster Tuning Remap today to Stuart, a long term, good customer of JGS4x4 with a Land Rover Discovery 2 TD5 Automatic.

Discovery 2 TD5 Monster Remap

Stuart recently found a ‘piggy-back’ tuning box wired into the ECU of his 2002 Discovery 2 TD5 Auto but was unsure if it was actually working. We advised to disconnect it and drive the car to see if he noticed a difference. Stuart said there was little or no difference at lower speeds but felt the Discovery did not have the same performance at higher engine speeds that the ‘piggy-back’ tuning box gave. He said the tuning box gave extra power but not until above 2500rpm.

I offered to carry out a Monster Tuning Remap and said he could drive it and try it before paying, if he was happy then he could pay, if not we would revert it back to standard.

We first carried out an in-depth fault code diagnostics to make sure the TD5 was fit and healthy before carrying on any further with the remap. There were a few minor stored faults but nothing to worry about.

The remap process took around 30 minutes, once completed, Stuart went off for a test drive and soon came back with a big grin on his face that spoke for itself. He was very pleased saying that the car immediately felt much livelier.

Soon after Stuart arrived home, he phoned to say again how pleased he is with the remap and wished he had done it a long time ago. He wants to come back in the New Year to have a de-cat pipe fitted, this will reduce the exhaust back pressure, helping the turbo to spool up sooner at lower rpm and reduce the turbo lag and increase the driving experience even more.

Thinking of getting your Land Rover Freelander, Discovery, Defender, Evoque, Range Rover Sport or Range Rover remapped? We can carry out a Monster Tuning Remap on most makes and models, not just Land Rover’s

    Thanks to JGS4x4 for restoring my TD5 to better than new, more torque, more power, less fuel and so much smoother to drive. Highly recommend it thanks to James and his magic laptop cheers fella and Merry Xmas to you all at JGS4x4

    Done 100 miles today, it’s changing gear great and the revs hardly go over 3000rpm where as before it was revving its arse off. I think it must be doing about 35 mpg now, a bit too early to tell properly but definitely feels better.
