If its 9psi intercooled with big tube kit 75 tb and 90 maf should see around 420. If you go to the web site the numbers they post with their 2.1 is exactly the same not sure why maybe testing isn't done yet. If you are staying stock block I would advise not going over 9psi intercooled. I finished my install about two weeks ago if you have anymore questions I will be happy to help.

The GT shortblock taps out around 440 WHP (max safe limit).

If you have an intercooled 1.7 you should be able to get 500~ or so out of it with the right boltons and motor setup.

A non intercooled one is an entirely differnt story.. I wouldn't go over 8 PSI with a non intercooled KB setup.

Full boltons(exhaust + intake)+ the intercooled 1.7 should see 420 with a good tune.
