I know Mike continues to work hard improving the Reflex for his future and current customers. Good luck on your choice.

Thanks Laynlo, I just have to sit back and wait to see what DSX is all about. I am all for a system that doesn’t add any extra controllers if possible. The direct plate system is the way to go and adding a better fuel pump instead of an inline pump is much better. If you can control DI and DP thru HP tuners that’s golden IMO. I am just getting advice and choosing the product that’s best for my set up. So if it’s ToohighPSI or DSX I am fine with that. My loyalty is to my car. Lol

What I read is the DSX can be activated and tuned from the stock ECU but there is going to likely be some sort of interface controller. Reason being there are no additional injector outputs on the E92 ECU, so something has to interface in that regard to trigger the 8 port injectors.

Makes sense. Unless he is retrofitting the LT5 ECU…probably not likely haha.

Talking to a builder/tuner that has a scoop on DSX direct port system. Josh sounds exactly what you said earlier about using the LT5 program into their system. Game breaking, hope it’s out soon.

Any updates on the dsx solution yet?

[radz28]

He seems to post a lot on FB. I don't pay too much attention.

PI controller should be out in a few months, if goes to Dave's plan. I think they list the bucket already on the website.

Any tuner can tune the THPSI REFLEX controller. It's about the same as meth'. I'm not saying it's easy for anyone but a tuner, but it can be learned if you want to do it.

It seems the 2hpsi kit is pretty ironed it and i know that's what my tuner uses alot.

I'm at the point where i need port injection. 906whp using meth and going to an f1a94 next year.

I'm not sure if i should wait or if the price would be much different anyway to make it really worth it.

You'll probably make more power going full DI (see BTR's video), and it would probably be simpler (more fuel lines and wires for PI) and cleaner, but you get a little benefit from intake valve cleaning, if that matters to you.

You probably couldn't go wrong either way.

What do you mean by full di?

I currently have an aux pump, +30 injectors, lt4 highside and +38 cam.

I believe port is the next step for me

Full DI means no port (just direct injection). In other words, he’s saying you’ll make more power if you increased the capacity of your DI components instead of going port.

The same much-discussed components: HPFP, LSFP, larger fuel lines, larger injectors...

I guess Im just confused by this because I was told by everyone that builds these cars that DI has a limit and I am there even with upgrading everything due to the high pressure needed causing issues no matter what is upgraded.

Is there anyone running 1200whp+ with full DI?

DI is only limited by available hardware…just like PI. As time passes, we’re getting better and better options. My LPE pump and injectors have me at 1059 WHP using DI only (on E50). I happen think that’s pretty decent lol. And now with the Goliath pump and available +70 injectors, I’d guess 1200 WHP is possible on E50+… and it DEFINITELY would be doable on race gas, probably even higher than 1200 WHP at that point.
