I think @ColonelAdama i’m going to readjust the duty bias back down to your settings. Getting some other passes and time I can see the overboost your talking about. What I’m realizing is playing with higher boost anyway, the fuel trims kinda ramp up to the 40’s pretty quick but then settle right...

Thank you, your an absolute Gem my brother!

For some having 2 parts to the tune they just don’t want to deal with it but what i’m finding is the backend flash has all the fueling, timing and other parameters kinda ironed out already and you can easily make fine tune adjustments to the tune in just a few seconds without having to wait for...

Yea it felt great too I just saw some 14’s/15’s AFR with high Trims and got a little concerned. the last map has the reset duty bias but you think I should drop it back down to what you recommended but leave the boost settings? If you don’t mind the Duty Bias is wastegate sensitivity is that a...

Extremeonlinestore Rep Streethunter less than half the price and looks great.

Ok so here are some logs @ColonelAdama This one is based on the settings you Recommended. I was trying to view it in the car and I was seeing AFR’s were creeping up and Trims were getting into the high 40’s https://datazap.me/u/phantomx2k/bef-jb4-ca-map6?log=0&data=1-4&hg=14-12-4-18-9 That...

Much appreciated will give that a shot on the way home from the office today! Logs coming later

I have the Extemeonlinestore rep street hunter wing. I love the way it looks. It’s over less then have the cost of the OG It fits really well. I have no leaking just use the supplied gasket. Being all ABS I think its a tick lighter. What I don’t like. Rear visibility in the mirror is...

@ColonelAdama current duty bias at 6k 56 then 59 then 62. current is 14/15/16/17 so maybe up 17 to 18? Lower duty bias to 53/56? yea getting wheelspin traction control light and 3rd fear pulls is more a thing now

This is with some updates and custom map 6 https://datazap.me/u/phantomx2k/bef-updates-jb4-map-6?log=0&data=1-4-12-18 Thinking about bumping up to e40 maybe e50 blend is the stock fuel system enough to handle it?

Watch out running MAP 5 without a tune. Run a log file and ideally send it to Terry or Ando at Burger to review and make sure your ok, you can also post to datazap.me I think and post the link to your logs here so a few of us can take a peek and see if it’s out of whack. I was running the same...

I mean that will probably buff right out right… unfortunately that was just pure dumbass. He was absolutely hauling ass, classic case of driving outside his skill set resulting in a rapid unscheduled vehicle disassembly with mass part relocation.

Update: New Starter New Battery DME Unlock MHD WIfi adapter MHD Burger backend Flash tune JB4 Custom Map 6 Should be right at 500whp Still $54999 pretty much every mod you could want on a daily driver

Just want to confirm which one works. I’ve seen the 18.03“ one and the 18.3” one and the measurements show 19” or does it matter as long as its around 18”?

I’m running the stock rims front/rear and with 275 Michelin PS4S and 13mm front spacers with 10mm rear spacers on the rear with a 305/30 and no rubbing issues, this should give you room for more track oriented alignment as well without rubbing the front strut. Also lowered on whiteline springs.

I just ventured, after a year of JB4, to the MHD side of things and i’ve been really happy with the results. Some real world dyno results playing with a few options and here is what I found works best. Current mods 2020 unlocked DME: Kanji Garage catless DP Injen CAI/Charge pipes Dinan Turbo...

Well I will give the PS4S’s in 305 a little street credit I pulled a 3.6 0-60 that was starting in 2nd gear and it was trying to spin like a mental patient on crack but between traction control (I just don’t turn that all the way off I don’t like meeting fixed objects while still in motion) and...

Yea I think that sounds about right. As for 305’s in the other post, Yea it’s a teenie bit out spec but I just look at it as extra curb protection ?

Honestly very little. Catted DP, JB4, 93 maybe cold air. One reason was it was the right amount of power for the tire on the car so it hooked up pretty good. Right now at almost 500 wheel horsepower. I did 3.9 yesterday. Pretty much spinning through second gear, third gear and a little bit...

The stock rear rim is 10” wide and a 305 works great it also keeps it closest to the stock 275 tires diameter which is 26.6 and the 305 is 26.2 the 295 is 25.9 almost 3/4” shorter in diameter. This affects gearing and Speedo accuracy. If you get to far out of whack with the front tire diameter...
