No kidding, You have a bigger engine than I do and I was pulling 183.0 [email protected] and [email protected] for torque with Gruppe M, Dinan TB, Dinan stg 3 SW, and UUC TSE exhaust on the exact same dyno machine. Seriously check the links to my dyno,s in my sig. Your printout is from the same type of dyno machine.

I know when I had mine done the second time the techs had a hard time getting some of the sensors to get correct reading for RPM. They had to make a few runs before everything was kosher and then they did my 3 pulls I paid for.

it looks like your car has high milelage. I'm not a pro at this, but I heard that if you don't drive your car hard, and that u drive locals all the time with stops and low speeds and low revs, your computer/ecu/chip or watever records it and will go according to your driving behavior, thus reducing speed, and maybe maximum output power/torque

How much is it to get your car dynoed anyways??
depends on the shop. Theres a shop here that does 3 pulls for 60, and you get a/f ratios too.

40 dollars if you get a 'dyno day' with multiple cars.

Ask around your area :thumbup:

Are you serious? Hell ive been driving it and saving the high revs only for occasions to keep my power longer!!! I gotta change my ways if this is true.

I drive the car pretty hard since getting the Shark injector, the miles are only 37,700, so that's not high miles. I don't know what happened. We did a simulated 0-60 and 1/4 mile run too. The 0-60 was 8.3 and the 1/4 was 15.8. I have done some stopwatch timed 0-60 runs and come up with 7.2. My car is an auto, but I should still be producing at least 20 hp more rwhp. Check out the numbers Edmunds got on a manual 328 on a Dynojet.Edmunds Dyno

Here's my suggestion: Turn your key to the on position for ten seconds... (DO not turn it on.) Then turn it off for ten seconds. Then start. This should clear out the throttle mapping in the ECU which can help. I presume your altitude was near sea level?

I seem to remember that this technique is for throttle by wire cars. Mine is a mechanical.

Good point. (Damn my poor reading comprehension!) Disconnect your battery. I forgot about that. My '94 325i ran significantly better following resets of the ECU. (I'd actually pull unplug it and let it sit for a few.)

I'll try that. Thanks.
