So after pining for the e90 I picked up a CPO '08, AT. I've never had an AT and I still miss my 5spd '00 328i but the pull in this car is too fun.

I'm having some wastegate issues that are yet to be resolved. On my second check engine light - first one was rectified. Second is yet to be serviced.

That said, what is the upper limits of the N54 without methanol? Is it safe to assume a 20% parasitic loss with the AT? I'm guessing 350whp +/-. I'm desperate to get this lag fixed but not until they get to the bottom of the wastegate issues.

Glad to be on board!!

Don't get me wrong - not worried about the tunes on the car. Just wonder what the limits are given:
Stock Fuel Pump
DCI
Upgraded downpipes
Higher flow exhaust
Vishnu product.

Looking for reliable hp - one where I spend less time on the computer and more time with my daughter saying 'Launch!!' from the back seat.

youll have to wait for part3 or 4 of shivs fueling thread lol

I would say start with cobb ap and a fmic. That should keep you happy

[wahoo]

^^ Hehehehe...read most of both. Good reads. I'm one that investigates over and over and over again before pulling the trigger. 99% that I'll get a Vishnu tune. Think DCI is coming first though.

you might want to do both at the same time, since without a tune, the DCI will actually cause a power loss. That and Vishnu might cut you a deal if you order both at the same time.

note: when ordering Vishnu products. do it on the phone. Robert is one of the coolest dudes I've spoken to with ordering products . willing to discuss shit all day if you wanted.
