Whoa whoa whoa. Read back a couple posts and my last one. I'm not comparing anything. He referenced the current M5 and implied that there must be something wrong with me for choosing the 335 over the M5. Other than that I agree with you 100%.A V10TT would be an excellent tuning platform and huge step up from my 335. Again check out my post up a couple notches.
