Excellent service and great quality of work. I had a stage 2 remap applied and the car now just doesn't stop pulling. Will definitely be returning when I'm ready for more modifications.

What can I say.. I called on Thursday morning and they got my van fitted in. Fixed the issue and I had it back Friday. Excellent value for money and great service. Will be using again.. Thank you for getting it fixed and me back on the road... Runs great now

I've owned my deisel golf for a few years and lately have been getting bored with it. Rather than shell out for a new car I thought I'd go and see Leo to see what he could for me. I didn't take much persuasion but I unleashed Leo to work his magic. A tidy remap, gains of 50bhp and a massive 80nm of torque, egr delete and something else I shouldn't really mention. I needed some other bits doing as well, cam belt, water pump, an auxiliary belt, anti roll bar, new brakes and pads all round and then thought, while it's in the air, sticknon some lowering springs and some new wheels as well. All done by Leo, everything including tyres fitted and wheels balanced. The remap has totally transformed the car, so much more power, 3rd and 4th just keep going. And not just the power, but if you drive it sensibly you can get rediculous mpg. Got stuck behind someone on the way home the other day, back roads from stow to hadleigh, and when i parked on my drive.....64.6mpg!!!!!! I honestly can't recommend Leo and Warner Performance highly enough. A top guy that does brilliant work. If you're local and what a little bit more, power or economy, from your motor, you'd be daft not to give him a call.
