Just got my first terminator the other day. It's bone stock. I just ordered high flow catted xpipe and flowmaster catback, JLT CAI. I want to do the pulley swap at same time and have it tuned. I'm not looking to overwork the stock blower but would like to see around 465rwh. Is that too much for the stock eaton? If not what setup should I be looking into? Billet flow pulleys seem to be my fav so far.

I hit exactly 465 rwhp with mine, with a magnaflow catted x pipe, borla cat back, JLT high boost, 3.0" pulley, and a tune. Bought a 2.8" pulley, but the previous owner screwed up the threads, so I couldn't install it. A lot of terminator owners install 2.76 and 2.93" pullies, and end up in the 450-470 rwhp range. Installing a larger heat exchanger can help reduce the heat from smaller pullies.
 
Also, it is very important to make sure your not maxing out your MAF and fuel pump duty cycle (fpdc). I would definitely have it custom tuned for sure. A lot of people ignore this!

I maxed my MAF and fpdc with a BF 2.76 upper, o/r x-pipe, catback exhaust, and intake. I had to get a kb bap and MAF extender.
