Hello all. So I started by changing my spark plugs and it snowballed into a total rebuild. Haha don't ask! So the setup prior to tearing it apart was pretty simple. 1000cc injectors and 255lp fuel pump. Stock exhaust with a high flow convertor, Plazmaman stage 3 intercooler and a stock turbo at 15psi. Lots of fun but as we all know you get comfortable with the power and so here I am. New build is a all forged bottom end, studs, ported head aftermarket cams pulsar gtx3584rs gen 3, Plazmaman upper intake, full 4" to 3 1/2" exhaust and all the boring stuff like billet flexplate etc. Well my question is how to break it in. Will my old tune be able to start it up and break it in? How long a break in before it heads to the tuner? Tbh it's my first non carbureted electronically controlled build. It was easy in the old days. This is definitely more complicated and I don't want to f/u a nice new motor.
