Very good resultz! What was your best/recommended launch technique?

JoeyB Benz

12.25 @ 115.58 - Traction Off - "S" - Launch at 2k RPM

12.26 @ 115.28 - Traction Off - "C" - Just Slam Gas on Green

12.22 @ 114.87 - Traction Off - "S - Just Slam Gas on Green


MY friend has a tuned BMW 550 and he launches at 3k RPM and pulls a 1.7 60 ft.


Next time I will try to launch higher.

I appreciate the feedback, thanx. If you try a higher launch, please report back with your results.

Thanks for posting your results...I want to get mine tuned as well. Any good kill stories?

JoeyB Benz

The tune is worth it as you can see the power gains from my track times 12.7 Stock to 12.2 Tuned


I raced a SRT8 Magnum Intake Exhaust Tune & BMW 550 M Sport JB4 Stage 1 - Both wins!

How much gain in hp/tq with the tune?

Nice run

So in comfort mode it ran the same 1/4 and trap as In sport ?

JoeyB Benz

402/443 Stock 530/606 Tuned (450-460 RWHP Est from Renntech)

Yes, in each mode it was the same, I guess when you floor the petal you get the power in either mode.

Worth the wait

I am assuming that is with your 19's on street tires.
Very impressive!
60' ?

JoeyB Benz

Yes LOL, acutally 18" Stock tires & full tank of gas.

1.9 60 FT.

mjec515

you guys think the m278 tuned can hit high 11's with intake/downpipes/exhaust??

JoeyB Benz

I will have the Renntech Exhaust on my car in April 2015.


I will be at the track, hoping for 11.99.


Im in NJ so I have great track weather. -2200DA in best scenario.

mjec515

nice...i have a '14 E550...all stock for now...waiting for AMS to release their down pipe and exhaust and intake....all i want is a tune and full bolt ons...

i see u have a e63 biturbo...how does it compare to ur tuned cls??

JoeyB Benz

The 4matic launches hard of the start but the e63 pulls at higher speeds.

rleggio3

What all comes with the renntech tune?? I have the same cls but should I tune it with aftermarket wheels?

mjec515

oh okay...theres this guy here in Alaska with a cls550 RT tune only and i guess it beat a '14 cls63 AMG w/o PP...idk the full details but all i heard was the 550 beat it...lol

JoeyB Benz

Yes a Stock 63 amg even with PP I would be confident in a win if not very close. MY E63 has the Renntech also runs 11.1@126 its a monster.

JoeyB Benz

Any ECU tune is so worth it with the CLS 550 as you can see I went from 12.7 to 12.2! I chose Renntech because of their history and experience. They are also more expensive then other companies.


On top of the tune you can add the intake filters and exhaust.


I will be putting aftermarket wheels on my car still deciding on 19 or 20 inch.

mjec515

wow!...i think it would be capable of hitting high 11's all day if it had launch control...yeah I'm just waiting for AMS to release their bolt ons and i will be getting those and bringing it to RENNTECH for a tune!...if i hit 11.9 with mine...ill be happy...i still wish i would've been able to get the 63amg but i couldn't...the 550 is enough for a 21 yr old...the budget AMG-LOL

Munich77

The E550 is plenty fast.... it will never be an E63 but I am having a hard enough time to even fully let the E550 stretch out its legs.

mjec515

congrats on ur new e63s!!! would be interesting to see how ur tuned cls550 will do against the amg!!!

JoeyB Benz

Thanks! I went 11.9@120 in the E63S it would be a close race!

JoeyB Benz

Went back last night in the heat 12.3@114


I have 20 inch wheels now and Renntech Exhaust


Shooting for 11.9-12.0 in November!




** And the Run in front of me is JPMBENZ in his 2015 C63S !
