I'm just going back to stock CR, I dropped for the piece of mind that it would make it reliable, but (I think) it has caused so many issues with exhaust flow and generally not burning the fuel well enough... James did some math and generally for a drop of 23:1 to approx 17.8:1, think thats the drop in CR anyway, then it needs 20% more air per stroke to make the same power as stock. I didnt think it would cause this many issues, and with HDi rods I will risk stock CR, f*ck it if it spews its guts again then I will probably go forged.
