Dinan tune?

[sy2767]

Searched on the Internet and it seems as though Dinan is the only one that offers a 35i tune. Does anyone have any experience with it? Are you happy with the results?

I've had the Dinan tune for several years on my 35i and have been impressed with it. It's a definite bump in power and torque. You will need to do the spark plugs with a one step colder plug. I recently learned it's a must of turned N55 engines.

My 35i has the M performance package so power is 315 HP and 330 torque. I wonder if the Dinan tune would be added to that or just replace it?

It all depends. I'm not aware of the "M" package on a 35i adding any horsepower over the a non-M package vehicle. My guess is it would be on top of that but that maybe a question for the wizards at Dinan.
