hey guys haven't been on in a long time, but anyways finally picked up my SS donar car (totaled) to swap into my 90 LS, has the black interior and all the goodies. harness and everything is being swapped into my LS. my question is if anyone has run the grimmspeed 38mm EWG uppipe, reason im asking is because I want to know how it got tuned (if at all) with the stock ecu or if Robtune/ wrx ecu/harness merge was used I was hoping to weld or get a bracket and close off the stock wastegate and run the EWG up pipe with a dump pipe and slap on a better downpipe to go with the 3'' straight pipe I already got with the TD04 or something a little bigger.. sorry if these questions are dumb, ive been away from the forums for awhile, thanks for any input
