After speaking to a few of the Ibiza boys about the removal of the n249 valve and the subsequent reservoir tank ( a few peeps have said it’s not that great anyway) I was just wondering if many of the leon boys have done it,. And if so what do they think? Or is it the exact same as the Ibiza?

Just wondering how many people have bypassed their N249, and out of those people who have reverted back? Since doing the bypass to my car it holds more boost but I'm yet to do a vagcom log to see how its going. I'd reccomend the mod to anyone but I've read of others reverting back, if you have why?
