I have an intake,exhuast,header on gsr=is the msd sci or the msd sci plus goin to do much=oh im not looking for stupid answers like huuu hes a trial member or stupid **** like that im he for help!

 

ur not gonna see any significant gain with the amount of mods u have now, but when u do get the msd get the sci plus or 6AL for the soft-touch rev control, u can mess around with raising and lowering rev limit/ 2step revlimiter and dont have to hear a gayass fuel cut-off and it sounds dang wicked
but for the $ ur gone spend, do some other bolt-ons at this point unless ur planning nitrous or somethin in the near future

 

what bolt on do you suggest? help
