First stateside ~400hp 135i
The OP was talking about 400HP Crank. I've never heard an AA tuned 335 hit 400whp regardless of the mods anyway. However with the Juice box tune and a catback ,FM , Stock Airbox and "Stock catted" downpipes I made 390whp/434wtq on a dyno jet.
I thought Terry made 400whp with just the JB2 with all the pills/R switch + race gas, simple intake and catless downpipes?
You're most likely right, but if someone's going to make a statement like that, I'd expect a dyno sheet, and not prsumed power. Remember, the 135 has a different exhaust than the 335. I don't expect it to make a major difference, buy only a Dyno will tell.
Apparently he was waiting for a few more mods before his dyno and the break-in period had nothing to do with it.
