Can you pull (read) the current tune from the car?

[HVR]

I think the car is pulling power. Either because of knock or something in the torque table. You need a tuner that is good with the lt1

Ok guys little update. Talked to the tuner and he admitted he forgot to change the cam timing, so I'm going back to him because he wants to make things right.

Wait... He's a professional tuner and didn't mess with the timing? I would walk away...

cam timing.. Im by no means a professional tuner but i have a decent understanding of an engine. I wouldn't expect he could do much with cam timing except adjusting when the variable valve timing kicks in any other cam timing is done by mechanical means. Maybe he meant ignition timing but that would be a pretty big deal to forget to touch that.

Here is an image, to show you where your issue starts.
Figure out what she's upset about right here, and you will find your power.

The curve should be nice and SMOOTH all the way up, even on a Mustang Dyno. (thats what we use here, and its calibrated allll the time)

yeah what he said ^^

That thing should be blasting you in the back of the seat by that point.

Ok so shitty update.
Found out that cylinder 6 7 and 8 are misfiring at that 4800 rpm mark. Ruled out plugs, wires, coils, and injectors so they are thinking valve train. So idk what I'm going to do, break into the motor and get it fixed for $2k or strip the car and selling everything.

How was the car before the install? I only ask because I'm just trying to figure out how your valve train went wrong from installing a Procharger.

[11bravoss]

Thinking it might have been failing slightly, and then the blower hurt it more. As of now it's only at a higher rpm under load.

[exxit]

I'd get a second opinion from someone else just in case... Hopefully they didn't shit the bed playing around with the tune and ended up putting you in deeper water, and are now trying to squeeze you for cash.

That's very impressive to say!!!

Are those the only mods done to this car?

What A/F ratio is it running, what's rail fuel pressure, is this an experienced tuner with LT engines - an tuner that is good at LS engines might not know anything about LT engines - they are totally different animals.
