Re: Turbo set up done on my LS Pics inside.
 

I assume I need a fuel pump because my basemap ended up very lean. My D series set up was very lean and I had to run a ton of duty cycle. At 8 psi at 6500 or so I'm at 92% duty cycle on my 450s. The stock pump has 190k on it and is 16 years old. I have a Walbro 255 I got from Tuner Toys and I also just bought a fuel pressure gauge. I may street tune a bit and then throw it on the dyno and watch the pressure.

yeah on the couple of LS's I've tuned, it didn't take much for the 450's to fall off with a stock fuel pump. I got one to about 8psi (maybe 230whp) before they maxed, tossed the walbro in and I had it up around 15psi and it was still keeping up, settled that car on 12psi tho (about 270whp)

I guess that's where I would want to be. I got some OBDI conversion stuff enroute! I can't deal with the map trace issues with TE.

Looks really good. I love the manifold and dowpipe/dumptube. You gave me some ideas on how to route charge piping also. I like it low like you have it. Looks good. 250 is within your grasp easily. I made 205 with a b16 t3 48/60 at 7 psi, small fmic, dsm 450, walb 255lph, PR3-->BRE with JD tuning.
