Anybody running this? The stage 1 system looks like what I need and priced fair.

Or is this just the LT4 fuel system?

Well I contacted Weapon X. Pretty much the LT4 Injectors and LT4 HPFP, with a modulator for the low side pump that only works for 2017-18 according to them. They said the 2016's have a weaker pump and recommends doing a low side auxiliary setup.

The only reason I am looking at other options is because the LPE pump is out of stock. Or else I would just do the LT4 injectors, LPE pump, and low side upgrade.

I have been checking everywhere and nobody has one. Every vendor says they drop ship directly from LPE.

I ordered their port injection set up. I already have it but I haven't installed it. I have the motor and trans out. I just finished building the motor and I am swapping to a built TH400. I am about to drop everything in the car and start on the fuel system.

Sixgun, does your TH400 throw any engine codes? I think you went from a M6 to TH400, just wondering. Back to your normal thread....

It isnt installed/running yet

FWIW, I just put in my DSX, second fuel pump, line kit (super simple) super high quality. My only comment is this my STOCK GM line from tank to hard line under the car had a bad kink in it. Since the DSX kit adds in a T fitting at this same location, the stock plastic line has to be pushed even further back, I straightened it out as much as I could but it will be needing a replacement. Point being with such a huge kink in it, no wonder why people are seeing all kinds of low side limits. The line from tank to hard line is plastic and heck of small and a good part of the bend is covered by a heat shield so you really can't see if it is kinked. Mine was kinked at is final bend after the heat shield / wrap and was easy to see. Grad I went with a second line....

Shouldn't throw any codes. Yes I am going from manual to TH400 but I bought a module that plugs into the clutch sensor and tricks the computer into thinking the stock trans is still there.
