Thats good information! Answers my question, i am using version 2 which is basically the same intake but the diameter of piping is slightly larger, with everything else the same. I am not getting a check engine light but after continuous hard driving the car blows out black smoke and the idle becomes very rough with revs jumping around. I assume this is a sign of the car running rich? Could my MAF sensor also be faulty? Do you think this could harm the engine in any way? And in terms of ECU tuning do you recommend hondata flashpro or haltech?
