I've been slowly working on putting together an all motor setup but now it's starting to look as if I'm going to move to San Antonio soon. If that happens I may end up scrapping the all motor project and just going back to a stock gsr then maybe a JRSC at some point. Now the block im building is using RS Machine ITR replica slugs, and I will be going back to a stock GSR head with GSR cams.

Since the compression is raised the one point will I still need a tune or could I just run a GSR ECU and be pretty safe?

 

some one has to be able to answer this
