I have an 05 with an E-Force and DR cams from Brenspeed. Along with Kooks LT. I never got the chance to dyno it with the Brenspeed tune because of how badly the car ran. It LITERALLY needed to idle for 10 minutes before I could back it out of the garage without dying. It would also occasionally die at a stop light. And I got 0 help from Brenspeed because they don’t do datalog tuning. Their explanation was, “ Hey, you got a supercharger and a big cam, it’s going to run bad at low rpm. Get used to it.” And it sounded like this, not much difference from stock.
I then had the car tuned by Lito. It then needed 30 seconds of warm up and it drove like a beast. It dyno’ed at 450RWHP/420torque. It sounds like this now.
. The only difference being the tune. This past June, I took the car to a track day at Autobahn CC outside of Chicago. While getting a number on the car in tech, one of the guys from LAPS, the organization running the event, came up to me and said “You have the best sounding car here.”
Last fall, I converted to E85. $200 for new fuel pump, $50 tune update. There was a HUGE increase in the butt dyno. Best upgrade ever! Because of COVID restrictions and then summer weather, I haven’t dyno’ed it yet, but I expect to be close to 500RWHP with Lito saying he left some timing out to be on the safe side. I plan to dyno in about a month, and have plans on taking it to the strip once it cools off.
