Hi everyone and hoping you can help! My daughter has a 2012 Twinair which has done 37k has been serviced well, including recent plugs and air filter. Car starts and runs perfectly but under full throttle load, it surges and is hesitant through the rev range. Having read a few posts it seems it could be the waste gate which does have some play in it when I manually move it. Before I swap it for an exchange unit is there anything else I should try? Thanks all!
