Happy day! Got my CL65!
Seems the car is gonna want race fuel for the high power so we are setting up the boost control to run at 93 pump and also 109 race fuel. They also were unaware of the killer chiller system so are no going to do some loaded dyno runs with the cooler running to see if that cures the rest of the gremlins. They did have to change issues to make the car perform properly plus fix it from blowing off the turbo pressure pipes. With any luck the car will be done and back next week. Just have to run two kinds of fuel in it.

sorry for the questioms, my intent is not to frustrate. Im just trying to determine what im going to do with my 65.
although, apples to oranges, I'm just trying to gauge where the tuning "really" is for these cars....




Speedriven has done a great build and Marcin with Jerry and David have done wonders to make this computer work. It required very little for me to get it to work better and I will share the info with them to help future customers. I do believe Marcin will step up and cover the retune cost as he is a good guy to work with and really dose nice fab work. i cant wit to see what the dyno reveals.
With the "Speedriven Tune" you had 622whp on Pump with only 12 PSI when I remember correctly, and now with the new tune on Pump it is nearly the same output? Hmm, seems they still had some difficulties with the tune at higher boost levels on Pump. But soon you will know more.
I hope the best for you with the outcome!
How are you switching between Pump and race gas tune, are you uploading via OBD2-Port or directly into the ECU?

It is running 18 with race fuel bu I know the engine can handle 14.5psi on pump so thats hwat I changed it to and verified with a wideband that the engine is happy.
I will get better pics after my detailer gets here today.


Even begun thinking about all those audio jewels yet?

Car does make 18psi on race tune and 13 on pump. Verified at my dyno shop. Problem is we couldn't confirm the 720/844 numbers from Eurocharged as his dyno stopped reading after 160mph for some reason.
Anyway, try running it in third, I believe that is what Eurocharged does because that is what they had me do even when I was on a dynojet.
