just saw this from the same tuner of the 840+whp e63... looks like they keep the tune even safer on this one and still made 750+whp

2015 e63s. Precision tuned to 752 whp. Upgraded turbos, intakes, exhaust.





and they also did a 775WHP CLS on only 22psi it was forced performance turbo, not pureturbos

Where are these guys located? My car may need to go to them for turbos and a dynotune.

new jersey

KLR CLS

Tuner is in NJ. Pure is in Oceanside CA.

awesome numbers !

CarHopper

May have missed it in the original thread, but what are these guys doing to protect the tranny? Are these cars going with upgraded trannies / clutch packs? Or are they just rolling the dice?

These numbers are no doubt appealing, but I don't want to grenade transmission after transmission just to run it.

gaspam

nothing done to tranny on the 840whp e63... nothing on the 750 whp e63

the CLS guy has had 2 bulletproof trans break before he even got the turbo upgrade from what i read, so seems bulletproof trans are not that bulletproof.... from what i read he is looking into getting Level 10 to build him one

seems like the stock transmissions are holding up better than the bulletproof ones

Fairbird

not my case for sure , first launch and boom at 700 FWHP , bulletproof last longer , 30–40 with way more power .

CarHopper

Yeah, too risky for my blood at this point. If I want to get to where these cars it seems that switching platforms would be the better move. No doubt the E is pretty quick out there compared to most, but I guess its just time to settle with the fact it won't get to that real monster level without a major failure/problem lurking in the shadows.

I remember how I felt driving my PFL C63 around without a warranty waiting for a headbolt to fail, no reason to feel that way in this car too.

But in the meantime I will definitely enjoy those who are crazy enough to go after those big numbers and low times.

Fairbird

I finally got mine back on the road


3 month later ...

gaspam

yeah true but i think your stock trans had a factory defect output shaft since you broke your output shaft before stock clutch packs even started slipping

Fairbird

yes I think so too , but really for that lvl of the car/price ..

chiromikey

Why don't we just wait and see what the tranny will hold before writing it off...

10speed

I agree 100%, I say the same thing the e63 with Renntech tune and mufflers is a perfect practical, reliable daily driver, without sacrificing warranty, you can run regular street tires and still put the power down.leave it at that

10speed

I had a Supercharged Denali and never broke the trans , my friend had the same in a Tahoe and broke countless transmissions ,same 4L60 trans, all input and output shafts snapping like twigs, He even snapped a $1000 unbreakable shaft from Raptor .Well we found out it was from the tune he removed all torque management , he thought he would get more power by removing it , Yeah but then you start breaking ****!

Fairbird

because even if they brake something you won't see it on here or instagram .

Amg63-

it might hold up with the power as long as these guys are not changing anything in the TCU

if they don't change that, the torque limits should still stay in place to protect the tranny. The downside is that no matter how much hp this car gets those torque limits will always give throttle lag from off the line and it really sucks.

chiromikey

Yes we will. This isn't Renntech

Amg63-

not to mention this setup with AWD providing over 600whp/700wtq will be enough to destroy most cars that try to touch it.

10speed

Yeah , exactly , I live in NYC so light to light for me,today most high Hp cars are rear wheel drive and if there not running the right tire all you see in the rear view mirror is a car pulling out of a pile of smoke ,and it sucks driving on the street with slicks , handling is just gone, I had a mid 11 second Buick Grand National and with regular tires once I hit boost up in smoke,it was useless from a dig on regular tires unless I had a slick , drag radials worked a little better,

if you remove the trq limiter on the 722.9 tran in our car the trq w/multiplication would be over 2400 ft/lbs to shaft in 1st gear so of course it would break lol that's precisely no tuners are removing the trq limiters

and if you look at most tuned dyno graphs vs upgraded turbo graphs on our platform you will see that the trq/ hp is about the same up until about 3.5-5K rpms and then after that's where the turbo upgrades start to put 100-200 hp over the tune only stock turbo graphs, so that is much easier on the trans than if the car had 100-200 hp more at 1K rpm

really the turbo upgrades arent adding that much trq, they are just able to hold it longer to redline, instead of running out of breath up top, thus most of the added power is up top not down low on launches where tranny is more likely to break.... so you chance of breaking tranny is probably pretty similar with just a tune since same trq /power down low... my renntech tune/dp dyno makes +50trq more than renntech turbo upgrade at 2500 rpm

TMC M5

Before you went stage 3, didn't you have Weistec tune your TCU?

Fairbird

yes , why?

TMC M5

Just curious if maybe taking the torque limiters out of the TCU software is what caused you to break some things.

Fairbird

TCU responsible for shifting and oil pressure , all the limits in the ECU , I had of the shelf stage 1 from them , no tq limits were removed . when I had bulletproff trans they removed them , I can tell the different in my 0-60 times
