You will often find that other tuners quote higher BHP figures and the reality is that more often than not, they are simply made up, to blinker customers into thinking that their mapping is better. For instance, we have one well known competitor who is 10% higher than us on every vehicle. So, are they 10% better? No, the reality is that they can use a spreadsheet! It’s about the quality of the drive, not just the figures. There are estimated gains but every car is different. we have a Dyno based in Dagenham so we can prove what we claim and it is where our development and testing is done.
