Civtek pointed out the upgraded throttle body.

TB looks stock I was referring to the LS7 blade style MAF. Much better air flow and better tuning capabilities.. as far as HP I'm not good at Trans loss etc, so I'll say 412awdhp.

What is a ‘street tuned cammed awd lsx’?

just curious. This is a stock ls2 long block with a cam and the items you listed external to the longblock or an iron LSx block with lsx 6 bolt heads and that cam etc?

+ Headers...maybe 365.

AWD and heavy wheels are going to kill your numbers.

To make 480wheel you're assuming you make 600+ crank with 20% loss.

On a smaller cam/headers engine. Nope.

Not counting you didn't list bigger injectors. If you're still running stock units you're not even close. I had to go to from the stock 28(?) to 42lbs after my cam swap. Otherwise it would lean out bad on the top and misfire. This was prior to the 402 build.

It's what PCM of NC put on their receipt for the tune which is gone now

Block is originally but again the problem is the work was done before I had bought the vehicle. Didn't pull the heads off so I cannot tell you if the prior owner did more work without providing reciepts.

I agree with the other guys about the heavy wheels, the stock injectors being maxed out, and you can only advance the timing so far with some good quality 93 octane before you start getting some knocky knocky action. You have some time to hook up E85 and also make sure your are running the correct spark plugs(search the threads) .... I'm going to guess 353 awhp

E85 won't help. He's already short of fuel injector.
