Count me in .

Any one ran into this also? I guess it should be the same for C8's.

They'd be amazing if they will support 6l80 .

This.

Apply the values in the cam card regarding degree of retards , although that cam is supposed to be for 5.3 L83/L84 not L87 so it's kinda close to stock 6.2 cam .

Bless ya

Yes, please.

Having the same problem, any updates?

Could it be a faulty MAF?

This.

Had this issue awhile back and turned out it was the check valve , just deleted it and it's solved .

Same thing , they started well but then I don't know what happened to them .

Best thing to do is going back to stock or move to another brand , I might give XDI a chance .

Those injectors are junk , take them off and flow test them , you'd be surprised.

Have you figured this out ? Having the exact issue .

Exactly .

Keep the good work man .

Had the same problem with a 6th gen camaro that was tuned before , if I ever change any parameter on the file regardless what it was , the car wont be stable at idle , I have ended up loading a stock...

No , im saying on a NA stuff usually 12.6-12.9 are the sweet spot on LT's , people still thinks the DI should run leaner than PI but for me dyno sessions proved that wrong , leaner won't help gain...

On pump fuel ?

Never gained 1 hp over 12.9 on these engines unless it's on E .

Bringing this up .

Anyone had luck getting the flex fuel option work on the SS ?

I see a lot of people on YouTube had it working , could they be using another OS's ?

you mean retarding it ?

Unless the LTFT is disabled also .

Probably a faulty sensor , get a new one and check .

Change the limiter source to GMLAN .

Well , if you got paid fully , your time and effort wont be wasted .

From my perspective , it's selfish to do that as I don't own neither the car or ECM .

I was wondering the same, anyone have some inputs?

From a previous experience, If you maxed the speed limiter it would show that phantom REP but maybe your case is different .
