This week's workshop job was Boyd's R33 Skyline.

The car came to us after having a MAXXECU, injectors and fuel pump fitted and tuned elsewhere, but it was pretty much undriveable. The rear of the car was covered in soot and the AFRs were miles off. Looking through the ECU tables felt like staring at a game of Tetris. To make matters worse, the boost control wasn't working and it was only making 8psi. It would also stall every time you pulled up at the lights.

We strapped it onto the dyno, fitted our PLEX V3 knock box and started working through the issues properly. Fuel, ignition, acceleration enrichment, idle air control and after-start fueling tables were all corrected and dialled in. We then fitted a new MAC valve and turned it up — with NO knock.

The difference is wild. Boyd now has a completely different car and it finally drives the way it should.

If you want your vehicle to behave the way it should SAFELY give us a call today!
