Map3, 93 octane and a can of VP octane booster. DA was 3172 per dragy, temps were not crazy high but humidity was very high.

Man, you are just spanking cars left and right...

I like the confidence of you knowing you just needed the camera pointing to the rear so you can see what is left behind. Do you know type of cars you raced and mods they had?

I was undefeated on the streets here in Mexico until this past Saturday. Somehow I got in the middle of a Corvette parade(probably 16 cars) and they were taking rolling hits at me. The 3 that took hits on me all pulled me from about 25 mph-70 mph. We never did a dead stop run, I may could've got them then. It was cool, as I was turning off from them, one pulled beside me and said "what ever that Thing is, it's bad Azz. None of us are stock. I gave him a thumbs up, turned off and still felt pretty good about the runs.

Stg1 Audi RS5, Challenger scat pack, Camaro zl1, Mustang gt, WRX, Mazda 6 speed.

As for the vette parade, those cars trap 120mph+ and closer to 130 moded, that's why I take my cars to the track, to get an idea who I can roll with in Mexico. That said, if you get the jump on anyone, it very hard for them to catch up. They need at least 100 extra hp and a couple hundred feet just to catch up.

Bite the bullet and grab the fuel pumps and e85 tune. Stock turbos you’d be around 570-590awhp. The flex fuel tune on my car is insane. It’s pushing over 700awhp right now. Car hates the dyno though and needs a TCU tune.

found a buyer for the GLC so on to the next one ! Lol !

Naw, I don't usually keep cars long enough to put that much money in. Plus this is my "work car".

I blew up my BMW on E30 or at least, all the sudden it became really slow so I ran to the Merc dealer and traded it in.....in Mexico.....

I see the X3M guys(my old group) are pulling 10.80's on a Mission tune now. Of course there are way more Bimmer Tuners than AMG tuners and way more people tuning Bimmers.

Either way,,,SUVs are out of control....

You are trapping 120 now, lets go get that Vette parade.

This was on maps 4 and 5, map2 might need cooler weather to run those numbers. As for BMW's blowing up, it's because they are running them on the ragged edge to get those numbers. Additionally, the e85 they're putting in them is most likely garbage from the pump that's been sitting in the tank for a while. If you want to be safe, buy VP85 in a sealed 5gal can.

Any idea on the Boost you are producing? I am sure you do if you are on Map5.

Very impressive. Please find a ZO6 to run and show me the video.

Do you see any issues on the street with this Piggy-back? In my BMW, the JB would fall on it's face at shift points.

Thanks, map5 is 7psi request over stock.
Map 0: Stock operation, JB4 disabled
Map 1: Default performance map, 4psi peak over stock, taper to redline
Map 2: 5psi peak over stock, taper to redline
Map 3: 6psi peak over stock, less taper to redline, suggested for E85 mixture or octane booster
Map 4: 6.5psi peak boost request over stock, less taper to redline, requires unleaded racing fuel or E85 mixture
Map 5: 7psi peak request over stock, less taper to redline, requires unleaded racing fuel or E85 mixture
Map 6: Custom additive boost profile, boost request over stock
Map 7: Progressive WMI (water/meth) mapping based on boost additive setting and WMI flow
Map 8: Low boost VALET / Safety map​​​​​​
I normally run 93 octane on map2 on the street daily and I haven't noticed any issues.
OTE=brad65ford;8110005]curious as well regarding how well the jb4 drives dailying with the piggy back jb4. I'm undecided to go with JB4 or Eurocharged for our 2020[/QUOTE]

I don't have any issues daily driving it.
I did contact EC before going with JB4, mainly because JB4 is a PITA to install on the 63 vs. the 43. I was looking into obd2 tune that allows you to switch stock too. However, EC does not have obd2 tune for 2020's yet (no one does from what I understand) the ECU must be sent for a bench flash. Additionally, there was no grantee that my stock tune will be saved. So I decided to go with JB4.

Yep but all the sudden BMW is remotely checking, flagging them and voided their entire warranty.That's not like BMW.
