Basline Dyno Tune at DC Performance in West LA 204hp 197tq (Stock)

I took my car to DC Performance today for a dyno tune. They're located in a little pocket in west LA right near the 10 and 405. Tony gave me the best price of 2 dyno tunes for $125 paid up front. I could use the other one at anytime in the future. Their regular rate is $75 for 3 pulls. My goal was to get some baseline numbers of the car in stock form and then come back after I added a few mods. I have essentially a Turner Stage 2 kit and I'm curious just really what it will put down.

I only briefly looked at the website so I didn't really know what to expect. When I got there it was evident they are a pretty Viper heavy shop. They also do a lot with VW/Audi and Mercedes though Unitronic tuning. Tony and Chris, who ran the dyno, were both enthusiastic about working with BMWs so it was not a shop concerned on only certain brands. I'm pretty sure they will work with just about any car as long as it involves tuning.

They had a chalk board showing some of the dyno leaders.....I didn't make the board.

Chris, the dyno tech, hooked everything up and took the car through three pulls. It was 65˚ and 31% Humidity resulting in a 0.97 SAE correction factor. I'm no dyno plot reader extraordinaire, but it feels better to know the numbers were corrected down and not up.

Best run out of the three resulted in 204HP and 197TQ. With 18% loss at the wheels I'm still putting out 240 crank with 138k miles! I'm totally happy with that. Chris mentioned that it was looking a little lean toward redline which isn't great. He suggested an old fuel pump could be the problem. I haven't looked into this to know if it's common with BMWs or the s50 to lean out up top yet. My plan is to run some freshly cleaned and tested 21.5# injectors with a TMS chip which will most likely change things up in the air/fuel department. We'll have to see if it's still lean up top after the intake, HFM, chip and injectors.

Here's a video of one of the pulls. It was much louder and cooler in person. Overall I was happy with my experience at DC Performance. The shop was clean and everyone was helpful and polite. Plus I don't think you can beat $62.50 for 3 pulls on a dynojet.
