Can anyone tell me if fse boost valves make a differance on rs2000's i have a 92 rs2000 which has already had a mapped ecu with a superchip on it and im looking to gain a bit more throttle responce just woundering if these boost valves make a differance?

any comments will be a great help

 

I think they do make an improvement with the mods you have but you'll need to have it setup properly

 

Heard good n bad about them..Never fitted one myself.A few plp i know have and not seen any increase in power..

 

not got one on mine, but did fit one to my mates 18 16v fiesta back in the day and it made a big difference. Just don't fcuk with the settings too much as it can go a bit pete tong
