The thing people need to understand about the 18k mod is that it adds the wow factor. What I mean is that it adds power down low be tricking the icp for more oil pressure, so you feel like you gained power, but you will more than likely lose power on the top end because your hpop is been asked for more with the 18k mod, so now you have less oil in the top end. That results with poor atomization and more heat with the unburnt fuel.
