AFPR With Speed Density Turbo Tune I spoke with one of the tuners at the shop that the car will be dyno tuned at once I get it back together, and during the convo when I asked about the regulator, he suggested that I do get an adjustable one. I've heard bad things about the Aeromotive ones failing but I see that Holley makes a boost-referenced adjustable one that's a direct fit for our cars as well.
The engine has 86lb/hr low impedance injectors, Racetronix dual in-tank Walbro pump setup with Hobbs switch. The fuel lines themselves are stock. The engine should make around 950hp to the crank.
My two questions are should I in fact get an AFPR? And if so, does anyone have feedback on the brand?

So you're running different fuel lines front to back? Btw, what PCM are you using since you're at 22PSI? Did you change over to an LS1 PCM?
Yes, from the sender a y block then 90* out braided line up each rail with welded -8 fitting at back of fuel rail. Front of fuel rail another -8 welded then braided line to fuelab regulator. Return is braided all the way back to sender then run a adapter quick disconnect off the hardline that connects to the return braided -6. That's the only part that's hard line on my application.
I run a F.A.S.T. XFI and XIM w/ a F.A.S.T. crank trigger along with 24x cam signal. Stock PCM only controls the factory guages in the car.

No problem. I'm not 24x though. I'm a hybrid of it. I just use their cam signal with their housing and coils. XIM controls the coils.
You've got a nice setup from what I've seen. You don't necessarily need 24x to up boost. I was running 18+ on a crane hi box and opti for years. LOL Just got to make sure you've got a 3 bar map sensor with anything over 14-15psi. The car will run better with CoP though, there is a definite difference vs single coil and opti.

From what I understand the LT1 PCM doesn't work well with a 3 BAR map since you have to cut the resolution down even more and it doesn't have that much to begin with. Did you have driveability issues on a 3BAR with stock PCM, or did you not really drive it on the street?
You need a boost reference regulator. No bones about that. As for ECU switch when you can to 24x efi. You build that turbo setup yourself on fquick? I've actually saved a pic or 2 of that car years ago. lol
My setup is pretty mild especially compared to yours but I'm still using the Aeromotive adjustable FPR and it's been working great for 2 years. I have 24x with hptuners and wanted to take advantage of the better atomization you get at higher pressure so I'm running 4 bar with no vacuum reference. Fuel system consists of: Walbro 255, stock lines, Ford 30# injectors.

Definitely looking to switch over when life permits. Did you partial fill your block? Are you driving on the street too?
