Not trying to do anything. I just don't believe you.

270whp > 250whp.
Your version of "laggy" is relative. 3500 is a while to wait for boost, I've heard it's more laggy then that from owners, but *shrug* I've not seen it myself.
Larger single turbo supras have a power band from 5000-8500, 3500rpm is a good powerband, but that's one fucking laggy turbo, isn't it?
Anything over 3500rpm is laggy in my opinion, but hey, that's all this is here, is a debate of opinions. You seem to be the only one arguing with me here.
