grr french electrics, 406 failed its MOT

[turbolag]

IMHO, there is a place for tuning boxes. I got mine on an offer for £170, used it for a year and a half (the performance increase was spot on and and totally MOT friendly, with no smoke test increase over the previous year) and sold it on for £100. A remap might have it's advantages, but refunding you in excess of half its purchase price when you sell the car ain't one of them!

You have a point you removed yours and sold it. But lets face it a tunning box is a bodge. It fools the ecu so it over fuels. You can adjust the boost at your lesuire. But to what? what is a safe amount? A superchip is a far more professinal way of modifying your car for starters your car is tested on the road and on rolling roads connected to laptop a tunned accordingly at a maxium but safe limit. So better performance is achieved without compromisung turbos ie tunnig boxes. Then the store all this data. Your car goes in they remove the original ecu program put it on your own key card incase you want it put back to standard. And they put there modified ecu program on. Also look back 20 years you will see superchips have been going many years look at the tunning boxes or cheaper remaps look at a new turbo and running problems. How many years have they been in business? SUPERCHIPS ALL THE WAY. Getting rid of the pug next year and getting a bmw 520d and the first thing i will be buying is a superchip they really are that good
