2014 Mustang GT COBRAJET new setup

[fluxy71]

I recently switched over from a previous stock 2014 mani with a JLT CAI BBK LTH, H pipe Roush axel backs quad tip exausts. , TO A Cobrajet ported, 47ib injectors, 65mm ford trin throttle body, Pmas CAI,BBK LTH, H pipe roush axel backs quad tip exausts. Both tuned by lund on 93/91 race tune. I went to do some pulls from 3rd gear and noticed the Cj set up accelerated poorly compared to the previous build. On my other build it would keep climbing past 100mph . this new build would climbing to 100mph and going slow. It really was a let down. The tuner said the AIRLoad was at .9 at WOT at 5k rpm and tapered off abit when it should be around 1. or more. He said it should be fine. I did not like the experience. I really need this to keep pulling and not stopping. I have a E85 tune about to be uploaded and hoping this fixes the problem. Any Personal Experts that can help or give me opinion?

Edit: I just noticed your ECU was tuned by Lund who, I thought, was the top dog for tuning Coyotes.
Sounds to me like you need another tuner, and I'd suggest Lito or HP Tuners.
