Switched to an Infamous Performance EBCS and the difference can be seen logging manifold pressure. Nothing dramatic, but every bit helps when you are fighting to keep your transient up.

Thanks for the recommendation! Looks like Infamous Performance no longer offer that EBCS and Delicious are the only one who carry it now. I was looking at the Delicious one anyways and I'll probably go with that.

any differences between PTuning and the Delicious Tuning one? They literally look exactly the same:

I guess the only difference I see here are the mouting points. Otherwise they are the same thing?

Probably not. They are all "Mac Valves"...in fact check this out;

The difference between Grimspeed and the Mac types (Infamous/Delicious/P-Tuning/Even AEM has an identical one) is that the barbed fittings on the Grimspeed are really small. Just that fraction of a centimeter in inner diameter, those couple little kunt hairs of open space for air to flow makes all the difference.

Wow. $35 dollars?? That's way cheaper than the others. Why wouldn't someone want to just buy this one then... at the end of the day it just seems like you're paying for the name if they work the same.

EDIT: now that I realize, it probably comes un-terminated and doesn't come plug-n-play. Probably would explain the price bump. Seems like polarity doesn't even matter either and a lot of other people are doing this on other forums:

do I bolt down overpipe then downpipe then turbo down to manifold? Or back wards. Dp seems to be touching cam angle sensor a little too much.

I have the same problem but I wrapped it in reflective tape to mitigate the heat.

[Amputechture]

My angle sensor touches too, pretty sure everyone's does. I did the same as Rybot mentioned, threw some DEI foil around her.

[choiboie]

so 30 miles and it melted the sensor everything still fine but I guess I’ll have to address this

maybe loosen all the exhaust bolts (downpipe/turbo/recirc tube if you have one) and move some stuff around to see if you can get an inch or so of space?

I used one of the MAC valves on my Rx7 for a many years without issues. If I remember correctly, they were exactly the same thing AEM and Haltech were selling at the time without the name brand sticker and mark-up.

What injectors and fuel pump are people running with this kit? It's going on my DD for the forseeable future so I don't really think I need anything above 700cc. PTuning recommended 850cc. I was looking at the Deatschwerks ones but people in the FB group were against them. Has anyone run them in the 86 platform?

I run Bosch 750cc injectors and they have been great so far. Imo you don't need to replace the fuel pump. I've had no issues so far with the stock one and I hear people pushing a lot more power than me doing just fine with it as well.

I've heard absolutely great things from James @HRITuning about the injector dynamics 1000 injectors. Apparently they are THE thing to use when tuning with ECUTek.

I haven't heard the best things about DW injectors, but I've never used them, so grain of salt, etc, etc.

I have a fully stock fuel setup (minus tuning, of course), and all is well. Has been for over a year now.
