For every day driving, I would say no more than 10 psi...with that there would be no risks, unless the wastgate stuck closed. I would say 10 psi and a boost controller and youre engine would be quite happy.

I guess the next question to go along with that is: How much torque can the tranny take?

thats amazing. I knew the ecotec was capable of great things, but i had no idea the breadth of it all.

On the link you gave I read this

"GM Racing began the tuning process on a Heinen-Freud water-brake dyno using the stock intake and exhaust manifolds and a modified stock downpipe plumbed without muffler directly into the dyno cell's exhaust removal system. It turns out a well-tuned stock 10:1 2.2-liter Ecotec in the above configuration actually develops 168 crankshaft hp (which is above the factory rating of 140-150 as installed in various vehicles in the United States and Europe)."

My question to all of you is how do you tune it?
