Hi, First off im new to turbo cars and modding them. I installed the Iceman CAI, it was a bitch, but i got it done. My car now sounds like a totally diffrent vehicle. This is normal? I think it is, just want to make shure. I hear my turbo winding up loudly, high pitch whine now. And also i get a blow off sound even though i have no blowoff valve, just the stock surge valve there. Is this normal? No loss of power, to the contrary i have a gain of power it seems. No vaccum leaks that i see, everything is snug. Car drives fine, no codes, nada. All seems good. I just want to know if these severe changes in sounds are normal. Heck i think my exhaust note changed also, sounds meaner. Please answer. Thanks
