J.l expansion chamber

Hi guys ive just fitted a J.L expansion chamber to my t5 what size jets should i be going with as i still have the standard 110 in at the minute and it seems sluggish until it gets half way through the revs then it kicks in with a belt of power dont know if this is how they work or if i should upjet any advice would be greatly appreciated cheeers[:drink:] [:drink:] [:drink:] [:drink:] [:drink:] [:drink:]

Welcome to the land of the powerband;D my good man. That is how expansion chambers work so keep those revs up and make it go waaaaaaaaaarrrrrrrrrrrrp.[:D] [:)] [:look:] [:rolleyes:] [:smile:] [:drink:] Oh BTW you will probably need to go up to 116 - 120 mainjet but keep doing plug checks to make sure you get it right.
