Hi Guys,

I have seen that a few cars have a 1 bar boost spring upgrade, I was just wondering how much difference this makes and if there are any pros and cons also costs.

Thanks
 
You should be fine using best fuel. Make sure your AFR's are good though after the upgrade because if you have any lean areas in the rev range at WOT you could melt your engine or at the least break up your rings.
 
No such thing as a stupid question bud. Air/Fuel Ratio : it's critical to both engine performance and health, too much fuel to air and power is down but fuel consumption is up, too little fuel to air and combustion chamber temperatures/pressures can rise to such an extent that catastrophic damage can occur especially at high load/Wide Open Throttle settings. The easiest way to check your AFR over all operating parameters, without installing expensive on-board monitoring instrumentation, is by the use of an exhaust gas analyser on a rolling road. This is my understanding of the terms anyway, if I'm talking 'keech' (a good Scottish term for poop!) feel free to correct me anyone [:)]

Agree, although personally I would rather have my own AFR setup that I can use time and time again. You can get one for under £300.
