Im dont really know much about timing stuff but its important.For instance,when i had my car tuned on the dyno for more boost,on the first power run the power curve was terrible.It was like at 170hp,went suddenly down to 70hp and went up to 170hp again.Grant from per4manz adjusted the timing and now the power curve is smooth,all the way to 245rwhp.Oh yea,he also says 12 psi is optimum boost for a stock R33 turbo.
13.6
