I've been searching and posting here at this forum and found nothing but great conversation. I was all about buying the kit even bragg about it to my soldiers hahaha. I know if I buy non I/C kit I can get my, LCA's, 4 tires, a dyno tune even KB site "say" they stand behind their computer chip and no need for dyno tune. Before I buy this kit, can someone pls. tell me that a 6 PSI kit really don't need I/C.
