I haven't posted to often on here but I am excited to share my build with you all.
Last year I purchased a 2017 C43 and after reading up on all the tunes AMR, EC, JB4 etc. I realized that they all having strong gains for tune only, but it just wasn't enough power for what i was looking for.
So i decided to team up with a local performance shop and that how the journey began. First I purchased a second set of turbos and sent them off for porting and new wheel.
Cooling was a major concern of mine so we added a generic meth kit to control IAT the meth also helped with the increased fuel demand. My car also has catless downpipes and Factory PE.
At this point i can't really share anymore build specifics, but i will say that I am loving the power and can't wait to get the car more dialed in.
I also want to give a big thank you to the team of engineers at my shop that put the time and effort into this project along with my wallet!
Track numbers soon to come as long as the trans continues to hold!
Thanks again to mbworld for giving us a platform to share our hard work on.
Do you know what your car ran stock for baseline? Otherwise the numbers do not mean much as I have seen huge difference in how each dyno reads. Otherwise what you run on track would give us a good idea too.
Woah, that's great load of power. Why not add the JB4 and use our FSB and meth control for it. You'd have the extra safeties and logging abilities as well.
Would love to see some videos.
Bump for updates. It's interesting that despite the bigger turbo wheel, power is still falling off around 6500 rpm. I was thinking the stock sized turbo wheel was why we were seeing a fall off at higher revs on other cars.
Any 1/4 mile trap speeds? If not, what are you expecting to trap? What are your estimated ETs? How's the stock tranny holding up?

I thought that was normal. Ive never ever seen a dyno graph (for any car) where the peak was at the very end of the rpm range, it always peaked 80-90% towards the end. Even the JB1 built-in Map2 settings have slightly lower boost towards the end of the rpm range. The boost peaks at around 5500rpm and at around 6200rpm it is half a psi lower basically.

The way I read it from OP, the porting and bigger wheel probably went on the compressor side, not the turbine side. Unless the turbine housing or wheel are made larger, the boost is going to taper off toward redline just like stock.
