Haven't thrown my intercooler on yet, but I've heard it opens things up in the higher rpm's a lot! Looking forward to your results.
Not sure, but you're likely going to need a TCU tune, and not necessarily for faster shifts (although that will help).
The car has some weird interactions between the transmission, central powertrain controller, and the engine, and ultimately it limits power based on gear and rpm's. Was the same issue with the 8 cyl cars. They were making bigger power but it wasn't necessarily translating into better times.
@Trekt43 got the cpc adjustment w the tcu tune already, Ive gone 303 kmph on the car feels lovely after the tcu tune and the cpc adjustment (the new facelift have this and it limits the tcu and the speed limiter), it was costly but so worth it prior to the intercooler

nice, it made a big difference on mine too. I have some consistency issues on some of the early gear changes but when every thing lines up the car feels great.
I have a pfl and it does have CPC as well however it is integrated with the TCU, or something like that. Different setup than fls which I think need the CPC physically changed? PFL guys are still going to want to look at getting it tuned
Pretty good, can't speak for day and night differences but it works great.
As for results, I am still waiting for optimal conditions to run a good 1/4 pass and im testing out some different values for the meth additive on the jb4 to make sure im hitting a right target PSI.
Throughout testing however, I can't say I see so much of a difference in the 100-200 km/h range, which is where I need improvement.

Which leads to me believe that this is in fact a very big possibility, since I am still running on top of a "Off the shelf" tune, granted it's doing wonders with the previous set up.
Still doing some testing so will let you guys know when I get actual 1/4 mile times in. 8.2 is the time to improve for the 100-200 km/h

Another possible issue might be fueling. Through 5th gear I still get some throttle closure and it might be fueling. I have a HPFP I haven't put on yet (waiting for an extra part) and I'll let you know if it helps.
With WMI you should be able to backoff the E85 mix (down to 0 even) which will help if this is, in fact, an issue.

It's hard to say if it's worth it. It certainly isn't cheap, and to be frank, it wasn't complete or fully tested when I got it (and I'd argue still isn't), which is rather annoying. I've had it revised once. When it works it REALLY works. It wipes off about 0.1 seconds, getting me into the 3.2's and likely the 3.1's as traction has become a big issue and my 0-10/0-20's are about 0.1 slower. This is on an aggressive ECU tune and the shifts are often not perfect, the car cuts boost and struggles to build it until the next gear. When that happens I run a 3.4-3.6. To be honest, that happens more often than everything lineing up.
The tuner thinks its not related to TCU tune and is in fact the ECU tune mixed with my fueling. But I'm running a relatively light e25 mix. My fuel pressure drops but I can't tell if that's a cause or a symptom. All I know is since the TCU tune... the shifts aren't always "clean".
Non-break boost launches and on stock tune the car is definitely always quicker. I ran a 4.02 on stock ECU tune with the TCU tuned and I've also run a sub 4.0 nonbreak boost launch on it which is really impressive.
I've been unable to run quarter-mile times but considering when the shifts are clean there is usually NO throttle closure during shifts (as mentioned above there is throttle closure through 5th) and the car holds boost very well, they will be faster

Yes, I am running 100% 93 pump in the tank with no ethanol or octane booster.
With regards to shifting, it does depend on how I start pushing the car. When I do pulls from 30-130 mph, I sometimes experience a pretty hard jerk from 3rd to 4th gear when Im running extra boost (from jb4)
When I get a good brake boost launch in, however, my shifts are fast and smooth the whole way up, so it depends really on where the car starts building boost I guess.
The idea of the TCU limiting power output is an interesting take however, could have hit the wall pre WMI and adding it won't make a difference unless the components allow to use the extra power
@Baterias NA i have a 19 w the tcu and the cpc adjustment and imo its super worth it, you gotta pay to play and now the car feels alive like very responsive and the added bonus of VMAX removed and raised torque limit, Im confident to say it feels like night and day for the facelift models at least w my tune 👹😈
going 290-300 kmph the car feels alive

Wow thank you for your comment. I just have not seen anyone got to 290 to 300 kmph. Did yours C43 get extensive hardware upgrade?

Considerin non-break boost I think it's already awesome to have one as my daily drive I just don't do break launches. Thank you so much for your comment.
@Baterias NA Just cpc replacement and tcu tune, costed me both in total about 4k CAD, it was a lot but it made the car come alive only if it felt like this out of factory stock, installing my intercooler and wmi tommorow so lets see how much more I can really pull out of the stock turbos, for the betterment for this platform !!
(The tcu tune in action as you can see I still have two more gears left to ascend in speed kind of scary/dangerous to take a picture while going 300 kmph but If thats what it takes for you to get a tcu tune and a cpc adjustment then I gotchu il post a pic going 300 tommorow or some)

That was awesome! So exited to hear that you gonna have intercooler and wmi tomorrow. That would definitely go beyond 300 kmph I bet. Be careful with the test run. I rarely hit 270 and it was already too fast
It's been installed and it works great (functionally). I haven't done extensive testing, but when I did try doing 100-200 km/h runs, I didn't see much improvement; I just ordered the TCU tune from AMR so we'll see if the modified torque management makes a difference with the power I should be outputting.
I have some numbers from the tuning w the wmi and the intercooler as well from dyno and testing w the tcu tune and the cpc adjustment however still gotta do some tests in real life roads waiting for the snow in Toronto to melt since it snowed last night
will post dyno numbers soon !

Let us know asap i got mine going in on thursday morning cant wait.
Everything is on and tests are ✅, **** sub 11s, we making 10s now
Did the dyno today and several test and I can gladly say that, Team eurocharged Jeffery aint the fastest anymore, I am. may the man w the fastest quarter mile win AND GUESS WHAT, NO JB4 FOR ME MUAHAHAHAHAHAHA
went from a trashy eurocharged tune stage 1 to a custom tune w full FBO and wmi and intercooler, **** eurocharged lmfao
mods: TCU and ECU tune, wmi kit, intercooler, fuel pump (hpfp only), intakes from bms, Catless downpipes armytrix
@DLinddd i do things at my own time, lets see what AMR and eurocharged got first then il reveal, as for slips let march come and let the car speak for itself, no e30 w jb4 adjustments here bud 🤣
speaking of slips, if your so into them show me yours 🤣🤣🤣🤣 my mods speak performance, slow dude Catch up
