OMG the car the car feels totally different. I put on my ERZ dp two nights ago (pain in the ass to install due to the bolts not wanting to come out). Now I have never owned a turbo car, when I floor it, it is really loud. I am pretty sure this is normal but I wanted to ask you guys/gals about it. BTW I have it mounted to stock cbe for now and it sounds nice with the turbo spool. Another question would an upgraded TMIC help at all or should I just keep the stock TMIC? I am running open source ECU with a wideband sensor that I will install soon and will hopefully get a tune in a couple months or so.
