Whats up guys I was finally able to install the return line (-6) and sure enough fuel pressure dropped. Now a quick question on idle when I drop it to 42 psi my wideband reads 10.8 and on the expressway it's at 9 on overdrive . I played with the fuel pressure and dropped it to 38 psi and now on idle it's about at 12.1-12.2 and expressway any where from 9.9-11.2. What do u guys think, should I leave it at 38 psi or drop it a bit more? What are your recommendation's for wide band readings? On the expressway it begins to sputter and being that it's so rich I'm wasting alot of fuel.
Wideband readings??

I'm running E85 with 80 lbs injectors and TT chip. I have ported stock heads, .30 over JE pistons, stock bottom, 212/212 roller comp cam, GN1 front mount, 6266 dual ball bearing precision, real 340 fuel pump from racetronix and hot wire kit, AEM fail safe wideband, and scan master.
Log files you can share ? or more information you can add ? ... how much boost ? what MAF on the car ?
I have an lt1 3.5 inch with a MAF translator. I put the correct settings for the translator. My Bl stays at 142 when cruising and drops to 128 at WOT which is fine at WOT but my concern is cruising it's running really rich. I haven't changed my O2 sensor ever and I've had the car for 3 1/2 years now so I'm going to swap that out tomorrow and hope the Bl drops.
