Both are PICCO based motors just modified by 2 different persons, both have matched piston/sleeve, the crankshaft's inner diameter of the JL tuned measures 7.50mm and it comes shimmed for 30% fuel. whereas IDM .12 is pre-shimmed for 16%.
my box stock IDM came with 0.4mm of shims and manual says it's ready for 16-20%...but manual stated stock is 0.3mm shims.
so...which is correct?
