So the last 3 days have been somewhat of an adventure. Took the last 3 days off from work to focus on the car for once. I had decided I wanted to retune to car completely using the TPS instead of the MAP sensor. So, I called up Lance (tuner that originally tuned my car) to come to Cali for 3 days. Lance had tuned my car over 3 years ago literally in an hour. Time was always cut short for my car for reasons like Bimmerfest. It was for this reason that I really wanted to get him over to Cali for a full retune.

We started the process by first wiring in a AEM FIC to my car. After this we went out in LA to drive around and tune the car for the street. We drove all over the place, hours in traffic, A/C blasting, it was 90+ degree's here. We drove to the main AEM facility and they did a photoshoot inside their race shop for their motorsports blog. (few pictures taken by my iphone will be below)

Lance literally tuned every little hiccup out of my car. We noticed the car had been running VERY rich so he leaned it out alittle bit.

The final day was spent at Specialty Z's (great guys) dynojet facility. This is where Lance wanted to tune wide open throttle on 91 oct and race gas. He really wanted me to switch to a flex fuel E85 setup but we simply did not have the time to do it. Regardless the results made me happy and the car has never ran like this before!

All the runs were using a very small shot of methanol which the car is not dependent on. Meaning I can turn it off and it will run just the same. Shout out to Drew for meeting up the night before and giving me some nozzles for the meth. I was running 2 large nozzles and ended up just blocking one off.

On 18-19psi, 91 octane gas we made 697whp SAE. You will notice all my graphs will be posted with a ZERO smoothing. Ive posted 3 charts below with various boost levels all pump gas.








Lance is extremely good at what he does and is a believer in smooth power over numbers, this is why I was so impressed. None of these dyno's were done to show off power, they are all street tunes and in my car. We put in VP Q16 and started turning up the boost. At 29psi we made 934whp, again zero correction factor. We also made sure the rpm signal was good and got actual TQ readings. You will notice how smooth the HP and TQ curves are.



The only problems we faced on the dyno was wheel spin and initial clutch slipping (needed to warm up). According to specialty Z nobody has spun tires on their dyno.

Here is the dyno where you can easily see the wheelspin.



We wanted to turn up the boost, but the Greddy controller simply didn't want to. We decided to keep it as it is, as it was running so healthy and smooth.


Here is a small video of 2 of the runs on race gas.
