'03 CL600 - Realistic 1/4 mile from ECU/TCU mods and drag radials?
Most info I've dug up shows the '03 CL600 does 12.4 in the 1/4 mile stock. Can someone shed some light on what a realistic expectation is in the 1/4 mile with the addition of a ECU and TCU mods along with a set of drag radials?

I will be able to tell in early april what that car can do in the 1/4 mile. I have a bit more work than just ECU and TCU tune but will have numbers before the intercoolers and billet turbos go on. I'm shooting now for 10s with a tire and all my mods are in my signature. I will be running 100oct fuel since these cars respond great to high octane. I raced my buddies 550rwhp Z06 on the highway which is about 1500lbs lighter than my car. Here are rolling results from the car on 93 pump gas and NO METH and NO INTAKES (REST OF MODS YES)

I just ran 11.7 at 117. These cars are so hard to hook with the open diff. Most my passes where around that or just terrible. I put in my 100 octane tune and mph went up about 5 but made it even harder to hook. My car is basically stock just tune and catless downpipes and different intercooler pump.
