M6 runs 10.3 on stock turbos
some people don't want to have to run meth all the time because if you run out you're screwed since you're tuned for it like in the case of running 133 mph. Previously that car did have meth but he was only using it for cooling and not tuned for it so it's no problem at that case if he runs out ... but now that he's tuned for meth it's a problem if he runs out .... my Audi b5 s4 was tuned for meth and it was great as long as I stayed in my city close to my house where I had extra cans of meth in the garage and could refill my meth injection tank, but I could never take my car on road trips without taking a ton of premixed meth water canisters in my trunk .... so that's not really a daily driver car anymore, whereas if you get upgraded turbos you can still go on road trips and fill up with regular gas and still trap way faster
What im really trying to get to the bottom of is when both M5 and e63s are modded with normal ECU tune on PUMP gas on STOCK turbos where the full drivability/reliability is working for BOTH cars, well then which one is doing better on traps and ET? Would you say under these conditions that BMW s63Tu still has the power advantage over the m157?
from what I'm reading while it seems like s63tu has the larger turbo advantage, it needs race or meth injection to actually use its full potential, but on pump gas it's only running like 80% of its full power. With e63s on pump it already seems to be almost at ful power potential minus the torque limits. So as a daily driver street car setup (street tires, normal everyday gas) I really am curious which one is the faster/better engine here?
i fully agreee once both are trying to be on full "race car" setup, forget it for now because m157 just won't keep up with s63tu in this situation. But that's very different than what most owners of both would be driving around with on the street as daily driver cars. So that's a different story imo.
gaspam, what would be your opinion about the above comparison?

weistec just came out with a meth kit / ASV that supposedly will give you 30-50 hp without tuning and up to a 100 hp with tuning ... wonder how long it is before people on here start calling their kit out and saying it sucks and is gay and all sorts of similar things
.... now you may say "well why doesnt weistec come out with dyno charts"... lol well , every time they do that people start saying " oh well i dont believe the dyno charts provided by vendors as they cooked the numbers" , but then no one on here will buy a kit without someone else doing it first and posting independent dynos.... lol lose lose situation for the tuners on this board
that's the funny thing... people have no problem accepting tuner's numbers for ecu tune because its cheaper and "safer" and someone is more likely to be the first to try it, but once it gets past a few grand all the sudden no one wants to accept the tuner's dyno numbers and wants someone else to go first and then complains that there are no customer dyno's
that's why BMW's are faster, because the guys over on bimmerboost are like "there is a new kit out? bro I'll get it and test it out!"... mean while on mbworld "new kit out? its too expensive! you need colder spark plugs/tuner said i dont/ tuner is stupid then.... any results yet asides from vendor's results? will this affect my warranty? can the dealer detect it? ..will it give me cancer?... its not worth it until the TCU torque limitations are removed! even with 1500 whp you're still not going to run a 60ft better than 1.6 with the tcu....gaspam is a farthead, no, kponti is a stupidhead... nuh uh, you are ! ... forum_memberX is a space rocket super science engineer and says forum_memberY is wrong because he is not an engineer".....etc etc etc lol

i never heard of "gorilla tuning" being used here on the amg. Is this considered a strong tune for the m157, would a tune from renntech or EC do better against the M in this video?
the m6 literally humiliated the e63 here. It's truly sad to watch.

Is this way off the mark or accurate?

are you going to pull up to them at the next light and tell them it doesnt count because you're not equally modded?

against AWD m157 of course. Im sure RWD from the roll would have a good chance beating or staying equal with it...

say if we were equally modded it could of been the opposite outcome.
I wouldn't literally "say" it but certainly would think that.
But either way, I already know on more of a "race car" setup the M is faster but on street setup where having s63tu tuned more aggressively than 127 traps takes the practicality/reliability out of the car it totally wouldn't bother me that I lost in that scenenario so I'd have nothing to think or say honestly.
you can always tell any s63tu guy that he's lucky your not modded like mr vasily's e63s LOL

My F10 M5 had BMS piggy, AMS catted downpipes, Agency Power C/F intake and Supersprint mufflers and trapped about 126mph in 500-1K' DA+. I suspect the full decat with much more aggressive tuning are the ones hitting around 130mph.
e63 4matic with tune only is better 126-128 without even needing downpipes.
These reallly high trap s63tu must be very aggressively tuned/modded.
I do really wonder how long an s63tu will last without major problems when being used as a daily driver boosted to 30 psi on stock turbos.

You're speaking generally, but I don't believe in dyno numbers at all, and I don't know who you're referring to when you say "people have no problem accepting tuner's numbers for ecu tune". I want to see 1/4 mile numbers, VBox numbers, etc. Yes, there are varying factors and conditions in these results, but those can be stated up front (as good business practice) so people understand instead of making assumptions. They won't do that because they know their mods aren't well tested or proven and they want us as consumers to do that for them.

I had S4 b5 , took me 3 weeks to get 900+ out of it , and 4 month to collect all the parts .
I've build S6 with 4.0TT took me 9 hours to get it to 740 hp and 11.0 1/4 mile , 9 HOURS !!! including everything !
plenty of info about porsche's , got it to 600 awhp easy with custom tune .
My GC srt8 , 6 hours to put SC on , 2 more days to tune it , 11000 miles no issues , 11.5 1/4 mile on that pig .
5 years ago I built firs 5th gen camaro , 7L , procharger , 1100 hp , I was one of the first who did it , took me 6 month total , with no part or info .
M157 platform out there 5 years already !!
I own benz almost year , the car is down for 6 month total , fun , some of it not tuners fault (I broke tranny output shaft) month was down , the rest is tuners , parts , etc .
I'm just going to put benz to stock, sell it , get R8 TT it and f@ck this .
after I'm giving it one more chance , since I still like the car
