Took my 06 CTTS to Union Grove in wisconsin. Came right off the 20 mile drive hot and lined up and ran 13.81 in about low 80s temps. Hot lapped it 3 times in a row best was 13.71. Let it cool down for about an hour and ran 13.54, 13.45, and then 13.37 at about 830 pm after temps had dropped to 71F or so. Best 60 foot was 1.97. Best result was lining up in manual 1st gear, brake boost to about 2100 RPM and let if fly shifting manually at about 6000rpm.

Just running a baseline but I was pretty pleased with those times. My goal of being solid in the 12s after an ECU tune, 2ndary cat bypass, intake, Plenum seems achievable with those bone stock numbers.

Just put the JB4 and DCI in my 335 as well, so heading up again this week to run that after a 13.60 baseline in stock trim. Looking forward to cooler weather for both cars

 

Cool. Good data point for the S.

 

I have heard that when you brake boost (apply hydraulic brake and press accelerator simultaneously) the ECU apparently down tunes the engine power.

 

If you build up enough boost, it will indeed close the throttle on you. I figured out that you can floor the throttle once the first amber lights up and by the time you launch, it will not shut down and give you just a little better launch due to a slight increase in boost off the line - but we're talking hundredths of a second.

 

nice times

 

Great times for stock runs

 

What did you get for wheels, and what are the offsets and rim widths

thanks
