There Mikolor clamps... A worthy investent... But buy them from an agricultural supplier / hardware... That way they are 1/10th the price than certain tuners (pointing no fingers) - a worth while investment... Dont think that would be the issue... Boost leaks are easy to identify if you've got a boost gauge..?! Or test it for leaks if you have a compressor, pressure gauge, 2 hose blanks and some air line fittings..See youtube - boost leak testing
