I haven't worked non high rpm on the base ve table either.... I'm slowly getting to boost...as you'll see I'm not ready to turn the truck loose....

See post 21.......sorry that's the tune....nowhere close to a 3/4 to wot run....
We're not laughing... we want to get you going...
A few quick questions...
What year/model/vehicle...?
What mods...?
What injectors (flowrate @ rated pressure)...?
Is your FPR manifold-referenced or not...?
Did you measure rail pressure (if manifold-referenced, temporarily remove reference hose while measuring)...?
MAF or MAF-less...?
Front NBO2 sensors...?
Hmmm....
what happened to HO/LO spark tables...?
shift pressure tables are maxed out...?
Thanks, I've had no help other than here and reading a lot....I appreciate the help.
1999 regular cab Silverado
2010 4.8 (lingenfelter 58x module)
411 ecm
4l80e built trans w/ptc l/u tc 3000 stall
Ported heads. Ls7 valve springs..ls9 can
Gapped top rings .0028"
Trick Performance front mount turbo kit and front mount intercooler.
Walbro 450 fuel pump and hot wire kit
Aem ungo wideband
80 lb surefire injectors
Will add alky when tune gets past 15 psi...
I own a Automotive repair shop... I specialize in auto electrical for 29 years....
On injectors the best I can calculate is 102lb or 12.08cc.
Fuel pressure is high 70 and I choose unreferenced.I unplugged the regulator to eliminate any possible vacumn failure.
Mafless SD cos3 tune.
There's two o2 sensors and a wide band on the down pipe...
My concern is my fuel pressure, one o2 is on the drivers header, other is in downpipe too.
