Start out with only a pound or two...

The best advise comes from someone who has already done it.....ME.

9:1 Compression
Cold heat range spark plugs
50mm wastegate
7psi
And ease into it......
Watch you wideband gauge
Anything Leaner than 12:1 under WoT back out of it, increase jetting.

There is No cheap method if you care about your investment/time.
