Is there a dvd to teach newbies all about tuning that would be relative to our delco 808's and how to avoid a meltdown?
I recently fitted a turbo to my holden 383 vp v8 and accidently blew the pistons out the mufflers on the first rev.

I'm rebuilding the engine and want to give the turbo another go but am very nervous about blowing it up again.
Is there a failsafe way to tune this at home with just a wideband and laptop with the ose12p?
With so many things in the ose12p that can be changed, how does a beginner know which should be touched and what should be left alone?
Thanks.
