OMG, YES if you're depending on meth, meaning if you're running boost higher than what the engine can handle without that extra fueling, for example you're running +6 psi on meth with fail safe set at +3.5 psi, at the moment of lets say pump fail the failsafe is supposed to turn your boost down to +3.5 psi, and if it doesn't your engine will detonate but if your meth is running at boost levels that engine can handle without the extra fueling, in this example it would be +3.5 psi, how can it do any damage ? The benefit would be better timing from meth as an alternative to racegas. Maybe I'm not understanding something ?

I just built the GTR with a stage 3 shep trans and I'm only making 700s on low boost... It would just baffle me if someone strapped big ass turbos on this car the rods/pistons and trans could just take that as safely as most of us are beating on the cars now in the high 500s/600s granted now that tuning is available they can smooth out the curve to help wear and tear, but still 700+ is 700+ lol. just curious if this is something I should reconsider when I dump the m4 getting back into the m5/m6 game |

This is all exciting and I can't wait to try it out....but this begs the question.....what the heck am I going to do for drag radials?!? I need some DR's I can drive around on all weekend without throwing a code!

The only time we feel safe using meth is by tuning the car for pump fuel then adding a soft mixture (windshield washer fluid) on top of it without adding any extra timing or boost. The extra cooling from the fluid can increase Hp a little by lowering the IAT's but if it fails the car is going to be just fine...just make less power. In this scenario it would serve the purpose of good intercooler system. Racegas is safer because as Boss suggested you are not relying on a relatively unreliable secondary injection system that has no communication point with the factory DME. ON race gas you build the tune for that fuel and and as long as you have that fuel in the tank you are golden. Eric Last edited by AMS ALPHA; 01-26-2015 at 04:52 PM.. |

If you went to say a MT 19" DR there would be no issues. The tire diameter is very close to stock height. Only thing is you'd look a bit goofy if you didn't have matching rims. LOL. I didn't give a shit myself and sometimes went out on the town with miss-matched rims. But I am not too confident of the sidewall lateral strength, plus I was driving on the street with only 25psi so no corner carving. Straight line fun only.

Correct I don't launch, but hard acceleration I do all the time. My car has held up fine with over 700 crank bhp for more than 55,000 km and it still feels like new. My point is that I would be concerned to drive with much more power on stock components. I have already heard of a failed tranny on an M5 with 980 Nm.

I dont know how the JB4 works exactly but I imagine it works based off of a stock map so putting that on top of our tune sounds like a REALLY bad idea. I will find out what boost we are running. Again the boost it runs at redline is lower than the boost it runs at peak torque as its starting to fall off.

Thats why I built it and even now I had them smooth out the low end to have power come on after 3.5rpms So I'm really curious how the m5/m6 will do with people just beating on it |

I don't even have a M5 and Im already done this entire thread lol. Im thinking of selling my X6 Activehybrid and if I do, I'll either pick up a 2013 CLS63 or 2013 M5. With the AMS tune, which one would be faster with just the tune?
I will probably get catless dp and an exhaust down the road but my first mod would 100% be the ecu tune. |

So far I've heard only eurocharged, but then again, no one logged it either.

You gonna tell me AMS tune doesn't run right? Somehow i just don't believe that. I have know Martin from the early AMS days and he tuned three of my cars he is a very good tuner and always gets the most out of a safe tune.
