Just my technique?
Most likely...Though I really don't want you to take that the wrong way...
You've gotta tap pretty hard to get a good strong tone, and even then you don't wanna overdo it cause then you'll pull the tapped note out of tune. Focus on doing it clean on a clean channel just to get the basic technique down and then learn a few 3 note arpeggios of your liking (classic Van Halen sus9 tends to be a good one) and then practice tapping these arpeggios on one string, maybe make a little 3 chord progression to keep it interesting. Focus mainly on dynamic and tone, getting nice rounded full sounding notes with each tap, applying just the right amount of force. Then gradually speed up, hopefully the little etude you've composed or 3 chord progression will keep you enthralled up to this point, and then when you feel you can play it at an amicable tempo add some distortion, maybe a delay (420ms) and let rip with some epic shredder chops. Then, and this is the part that requires discipline, once you're done treating yourself to a short wailing session turn that gain and that delay off and then sit there with it on clean and slowly build up tempo again ? That way you can compare between with and without gain technique, make sure you're muting correctly etc ?
You could also add a light bit of compression on the clean channel, this will even out the notes and get them nice and even in volume, however you don't wanna overdo it cause the more even the volume curb becomes the less dynamic your sound will have ? I don't advise using the compressor on your distortion channel though as overdrive naturally compresses so it just thins out your sound if you add more compression. <--- You possibly know all of this already but it may help someone else ?
Guthrie Govan and many other gifted players manage to tap out long fast passages with entirely clean tones so it is definitly possible ?
