Lets talk about fuel, pressure and ECU's
Here's my current setup:
TS ECU
Crawford Plenum
350 Throttle Body
UR pulley
AEM CAI (heat wrapped)
My question(s) revolve around the fuel system. Did anyone w/ a TS ECU get documentation talking about the reccomended octane level? I have run 104 and 110 (small amounts) with no noticable difference.
What LPH is our stock fuel pump? I know in some other engines, a new fuel pump w/ a higher fuel pressure regulator, can make a huge difference.
I am a little dissapointed with my gains after spending close to 2K on the engine alone. I have not gotten the car dynoed yet, but don't have a baseline anyway.
The problem with installing mods together is that you never know which mod makes the most difference and if one or mods actually hurt performance.

I don’t think running anything higher than 93 will help on this engine in stock form (or even TS ecu form).
One thing I notice on your mod list that I would change. I would yank the AEM. I think you will be better off with a stock air box. I have seen it first hand and have heard confirmations from too many people that it does more harm than good. As far as the fuel pump goes . . . it is fine. Ask 12secZ how his lone stock fuel pump is doing with larger injectors and a TS flash for his Procharged Z. We have one here running the same setup.
