Does my dyno chart look right?

[YoshiBishi]

I feel like my torque band drops pretty significantly and also isn't as close to my max HP as other dyno charts that I have seen. Perhaps the tuning is off?

I am also getting misfires if I go WOT around 5k rpms. Sounds like I'm popping popcorn in my exhaust. Not sure if this is something broken, a bad tune, or the AFR isn't right.

It was hesitating and bucking as well. I disconnected the ECS and it stopped hesitating. Now, it seems to hesitate when I try to start it up. It sounds like the engine is bogged down. It always starts, but it acts like it is straining.

I have new plugs and wires
Walbro Pump and Hotwire kit
Krank Vents
Catch Can
3sxecutioner kit
Fuel Rail Adapter Kit
550cc Fuel Injectors
GM Maf-T with Dejon pipes
Ebay downpipe
3sx Single Pass radiator

I just got my 60k maintenance done as well as getting almost every hose and line replaced in the engine bay.

I've only owned the car for <500 miles, was bone stock when I purchased it in beginning of December and was running perfectly, ECS was working too!

When I got the downpipe put on, it started bellowing out smoke and I burned nearly 4 quarts of oil in <100 miles. The rear turbo failed which resulted in having to get all of these mods put on. Now the car runs horribly at WOT. Should have left her stock
