What would be a good turbo to replace the GM-4 turbo? I am looking at a A-Team turbo. Id also like to know whats the max boost I should run. I hear 12-15 is the max and stock is 7-8. Id like to know a few things that will improve performance. The few things I have is a 4" Exhaust and Air pod filter and also a 80hp 160ft/lbs chip from SSdiesel Supply. I have gauges just not hooked up yet. Id like to know a few things I can do to get the most out of it. Just let me know what you know and thanks for all the help.
