If you are turbocharging an engine like the OP is planning you should begin by driving it like it is not yours. If you pay attention to the boost gauge you can not get a major boost spike. If he is careful with his tuning, he won't have any problems. I don't see how anyone can miss the fact that the boost needle goes past your wastegate pressure. When I was tuning my electronic boost controller it would spin beyond 13psi where my wastegate is set. Yet I wouldn't let it spin beyond 15-17psi. Its not that hard to do even on public streets.

No one with a brain will take their freshly built turbo car out and proceed to do a fourth gear top speed run. That is idiotic. You carefully sneak up on your goals. I don't know what turbo the OP has but it won't do 30psi much less 40. If you miss the pegged boost gauge you probably shouldn't be working on your own cars.
