Im getting the blouch 20g xtr on my 2.1L.

Im novice and only going on what many other people from many different forums or workshops are saying. But apparently the 20g hits harder that that 1.5... but doesbt quiet have the same top end.

All have said the seat of the pants feel of the 20g will be better
