Some may know, I am building an all motor LS. Which consists of 11:1 compresion via PR3 pistons, new rings, bearings, gaskets... OEM 3 layer headgasket, hondata intake manifold gasket, 62403 cams, skunk2 intake mani, JDM ITR header... I was told by a friend of G2IC that I would need to run at least Hondata S100... because of the jump in compression. Is this true... Please help... I may end up ordering it tomorrow, but want to make sure there arent cheaper routes to take. Not that I want to cheap out and cut corners, but if there is a way to spend less and get the same results, I woud like to know what it was.
