What should I run with my SR, other than just a boost gauge? I'm thinking Oil pressure? Also what other electronics should I get besides a turbo timer? I'm thinking a boost controller but are those really necessary? I plan to get one later but is it necessary to get it when you just swap the SR? I know this is a stupid question but what exactly is the diff. between the manual and electronic boost controller? Pro's/con's and how they are adjusted?

 

Oil pressure is a real good idea, and boost controller isnt nec. unless you are ganna be boosting
