If you blow-thru, you get a more acurate air intake temp, if your MAF has the temp sensor in it, than draw-thru. Also you can put a BOV in without having any stalling problems. You can get around the temp issue by just wiring an external temp sensor and putting it after after the intercooler. The stalling issue isn't fixable, but a little careful driving helps keep you from stalling.

Forget the HP, look at the TQ figure. Yeah, nitrous is weird with a turbo. Because it is cool and you're compressing the air, you get more power than if you juiced just NA.
