Meth Kit - Yes or No ? and Why ?

Can anyone (With experience) advise me with Meth ?
1) Is it Safe ?
2) Does it require Re-tune after installation
3) Can I run it 24/7
4) Several cases of catching fire/blowing engines have been observed. whats the main reason.
5) Does it give GAINS or it just cools down and gives you back the lost power.
6) Can you share graphs or timings before/after meth


I got F06 M6 Gran Coupe 2014 with the following Mods:
VRSF Catless DP
M Perofrmance By Akra Exhaust
ESS tune
Eventuri / No Scoops

Output:
625-645whp uncorrected on Dynojet
850-898Nm uncorrected on Dynojet
6.8 Seconds 100-200km/h on Dragy

1) No, From my own experience Leaks can happen from any point which is so dangerous.My meth tank started leaking and i found out the all of my car trunk was full of meth , any small spark would of burnt my car ( took the meth out the car since then )
But, if you maintain it well and check for leaks weekly maybe thats for you
then. but if its a DD i wouldn't want the extra work that comes with it.

2) yes

3)It doesn't run 24/7 it only runs when you are in WOT

4) Leaks, Since if it leaks and the engine is using the Meth for fueling then the engine will blow under load.

5) Gives Gains , But comes with a cost

6) If you want i have some JB4 logs , ( logs of the car fully tuned without meth ) , ( Then logs while Fully tuned for Meth )

So meth didnt workout eh? You still running pure stage 2? What psi are you holding? Also, did you get that issuenfixed where psi was dropping from 20psi to 16 psi?

JB4 is out & Never back again in my life

Flash only + MHD - is the best option

Dont buy a JB4 - Just look for a reputable tuner that can tune your car through BM3 or MHD

No Meth Again
yes PS2 is still in the car

the issue isn't fixed, but the issue isn't with my car only, all of the F10's 535 that i know about they cant hold boost on redline - we still dont know why but it seems as air restriction going on in some place in the car

Damn ok... let see how my car does. I am hoping to hold at least 18psi.

I wonder if it is because of jb4? Have you tried getting it tune without jb4? I mean if you not going to run meth then jb4 seems pointless :P. Should go straight to ecu tune to see if that makes a difference. You already got mhd flash tune done.

But if you want to keep jb4 then you should look into chargepipe injection from fuel-it and its cheap. 900cc injector can support up to additional 100whp.

@MissionPerformance has a fix for holding boost to redline on the ecu but it's more of a mechanical limit. You have to upgrade to pure 2 and flash
