I've seen dyno chart from a E9 with ralliart ecu and ralliart intercooler piping kit.. looked respectable to me.. anyone here with experience with the thing?? Notiguy??
currently im using gsr intercooler with stainless steel piping
i wanna upgrade to vr4 intercooler with piping
wonder how much would it cost?
and how long it can be completed?
any shop to recommend?
