Thanks for the replies guys. Without the tune from a 20 roll like this he typically put a car length and a half on me or maybe a little more. Now as you can see I beat him and we did it two more times with the same result. I personally dont think a 335 is as fast as many people make them out to be unless they are heavily modded. a light tune like this one from oe tuning isn't going to give them 400 crank hp like their tuners always claim. He says he's putting 350 hp and 360 torque to the crank with his tune and that seems believable. His car also is pretty heavy and my car is a base. I think I'm probably at 340 crank hp right now by the way the car is pulling. For the 700 dollars for a gear change I would just keep my 3.31 and get headers and a mid pipe or a new driveshaft. Number one on my mod list is tires now.
I think a lot of those "stock" or "lightly modded" 335 that go low 12 have more than just a tune like they usually claim. Down pipe, a very aggressive tune, boost controller, and full catback and usually slicks and the 335 can reach 400 rwhp, they responsd well to mods. That's what I think those 335s running low 12s have but they just lie or don't say all their mods.
