Hi, so bear with me here as im a turbo newbie. My S3 currently chatters, which i think is the result of the dump valve being in backwards? Or possibly the N75 being deleted? Im not sure... But its got the standard dump valve in place, n249 bypass. So i want to get rid of the chatter as its not good for the turbo i hear. So should i be looking to replace the standard dump valve with a Forge item? If so what are the advantages?
Engine spec; APY, stage 1 remap, FMIC, forge TIP.
Thanks in advance
