    Do you think I can get away with running a catless downpipe with an external wideband o2 that fakes the value back to the ecu anyway? (from plx if you know them)

    379+495+140 is a pretty decent...

    I have not purchased a tune because none seem to be suitable to circuit driving and I would rather pop an engine out of warranty if I was making 350+hp but Terry@BMS said that would be a couple of...

    Assuming non-gdi knowledge, I based it off the 335i having 70% duty cycle from the factory and we have the same injectors (as well as a ton of others including the 740, e90's and some of the suvs)...

    I believe this is the only way this car is going to go much faster. Anybody not looking at a new turbo is kidding themselves about the ability of a mitsu td04-06 at 21psi. I have yet to find the...

    Terry @ Burger is the only one that I have talked to about it much but their graph alone indicates tip-in detonation. He seems to indicate that the stock engine doesn't even run well on 91 octane at...

    I drove a 135i with a COBB tune and it was ok other than his check engine light, but I thought the stock 135i was more driver friendly other than lacking power on the straights. This could even be...

    I think this is a major point to help HPDE drivers. I would even be willing to change the turbo to get smooth power delivery even if the peak is the same as an overboosted stock turbo.

    So far I personally only have 4, 20 minute sessions on this car and aside from having to change my braking zone the car was fine at the track and the brakes stopped squeaking a few days later. I...

    None of the tuners seem to be releasing much in the way of data so there is no real way to know if one is 35psi and 15:1 A/F so cost seems to distinguish them the most and BMS with their beta seems...

    does anybody run track days with tunes?

    Real world experience with any of the aftermarket tunes? I am reasonably happy with the car but mathematically the 6th root principal dictates that a 1:35.0 lap time would be 1:32.5 with 279hp and...

    This is a general opinion because I can't find the exact compressor map for the TD04-LR6 in our cars but I don't think there is anything left in the stock hardware (turbo and injectors) to allow...

    It doesn't seem like it would be that hard to source a turbo with the same turbine housing because bmw's twin scroll design is really just cyls 1/4 and 2/3 powering a different part of the turbine...
