If I am not mistaken, his forum name is URNext. I don't see him on the boards much.
What kind of 1/4s have you run? I have similar mods to yours and have a PB of 11.8 on street tires.
I don't list my mods, but they are, RT, 172, RT HE and pump, 80mm TB, EvoSport shorty headers, secondary cat delete, and phenolic spacers between the SC and on the intakes. EC dyno tuned.
I would suggest a heat exchanger first to help keep your IATs down although that won't add power just make it more consistent. We know from the E55 guys that when you get around 500 WHP you are in the realm of toasting old number 8 under long pulls like through the top of 3rd. So as mentioned above, I will suggest a fuel rail and injectors as well. They are my next mod for sure. They add some power and keep number 8 from going lean.

Haven't made it to the dyno yet, but I'd think my car should put down some nice numbers. The only thing holding it back might be a conservative Kleemann tune, but I'm fine w/ that because mine is my daily driver and I don't want to have any issues w/ fuel.

You def have the combo for big #s. I'd like to see what your car throws down. Jeremy from OEtuning got 40+hp more out of a Renntech (stage 3) tuned car. Blew my mind.

you need to slap some drag radials on that bad boy and run it down the track.
