Hi guys

I am fearly new to this forum. I run a PGM CDI chip in my 21 obviously with the correct loom to fit it. I bought a PGM 3 + loom and swapped the loom and chip hoping for more power and feel for the bike. The PGM CDI has more grunt than the PGM 3. The PGM 3 loom is spliced and all done correctly. Is it possible for a mark 1 MC18's chip to out perform a PGM 3?

And please correct me if I am wrong, the PGM CDI with the two boxes does come from a mark 1 MC18?

What chip would be best to keep in my bike?
