Hey guys dont know if I should post this here or what but Ive been wondering about this for a little while now, I had a new motor built in the spring and I think I may have gone a bit too small with the injectors, the motor is a 355 10.6:1 comp ratio, HSR, zz4 camshaft, 52mm TB, 1.5 roller rockers, with Accel 26# injectors. I had a custom chip made up by pcmforless and every time I do a datalog I check the histogram out to see how the fuel is looking and evrey time it goes into closed loop mode it heads straight to the lean side of the board and stays there. Ive sent the chip back along with a datalog to have it corrected but still the same thing. I am slowly working at putting in a holley hp efi system and was just checking out a log from a couple months ago. Its been bugging me for awhile and the last thing I want is to melt a piston cause of a lean condition. Oh yea and the injector size I was thinking would be about 30#. Any input is greatly appreciated guys! thanks for your time and wisdom. Take care

 

Personally, I don't think your injectors are the problem, sounds like it's more in the chip to me. I had 26# injectors in an old combo that was 355, big solid roller cam, mini ram, and Canfield Alum. heads. Combo made 525 HP at the crank, and I had plenty of injector.
