your injectors are way to large, i say its the tune...42injectors are wht i got for my 408.. my old 6.0 had 30s and which was more then enough

 

the 42 SVO's are way too be big for that..did you tell him that they are just 42lb injectors or 42lb SVO injectors..because the 42lb SVO injectors are actually about 48.xx lb injectors because they are rated for 43 psi fuel pressure..and your truck is running 58 psi..that would make it run like **** for sure..just find some 30lb SVO red top injectors..because at 58 psi they are around a 35lb injectors and that should fit your mods perfectly

 

They are 42lb svo's and its a wait4me tune, Jesse said he could tune for the additional size??

 

There is a guy in Albertville that is really good at tuning, Scott Culbert aka. Gomer. He does dyno tuning in Trussville and Huntsville. PM me it you want more info.

 

Can you pm me his # or give me a way to get in touch with him?

 

my old 6.0 thats 11.1 cr with the trex uses svo 30#s and at 82% and thats potent combo. this should give you an idea on where your injectors stand at

 

those are a bit more than 30 though,
my heads/cam 6.0 is runing at 98 to 99 idc on stock 8.1 inj's.

 

svo 30s are 36# injectors

 

I went to dealership and borrowed a fuel press. gauge, I had 60psi idleing and if I blipped the throttle it would dip to 55psi. Jesse at w4me said it will probably dip to 30psi driving it. heres my fuel system; stock 99 intank pump goes to a vette filter/regulator,I basically plugged my lines off my stock intake into this filter/reg. My fuel rail is a single line off camaro.I am running this same setup on my 69 camaro ls1, with no problems. What do you guys think about this setup. Should I go to a 255lph pump and a diff regulator?

 

TTT Help me out guys, I need opinions on my fuel setup,and open headers was alot of my above problems, o2's dont like open headers. I'm a dumbass and I learn **** the hardway.
