Installed GT350 manifold and TB runs like garbage

[Silver50Pony]

Had a GT350 manifold and TB installed with ford 47 lb injectors, then dyno tuned and it put down great numbers 430 rwhp and 369 torque on dyno jet. steeda cold air and corsa catback only other mods. Driving it home its bogging bad like real bad, doesnt wanna accelerate all gears. Contacted tuner with datalog but like to get a second opinion.
I have the datalog if someone is kind enough to review it for me that would be great. I want to make sure its just the tune and not the parts installed incorrectly. Checked all connections and everythings snugged up. I am going with Lund tuning 100% shortly anyhow. So if anyone can review a datalog message me or any tips appreciated.
thanks guys

datalogs won't help you. tuner needs to rework the cam and IMRC tables.

As long as you think it's the tune and not the install , tunes the least of my worries. Was thinking it could possibly be 47 injectors too not being tuned right? Maybe dumping too much fuel at low speed cruising?

The place that dyno tuned it didn't drive the car afterwards? I don't get shops that tune car but do no test drive afterwards to make sure the drivability is ok.

I take it the place you took it to has no experience tuning the GT350 manifold? It wasn't Mustang Magic I hope.

got mine done last tuesday with stock tb. put down better numbers but surging in low rpm lite throttle and not as torquey. went to the track and its not as strong till the 1/8th. picked up maybe 1 or 2 mph but about the same et maybe a little worse i got the a6 with 3.15 gears shifting at 7500 rpms. gonna raise my shift point to 7700 and looking into 3.55 gears.

Gears won't help you, you need a converter.

thats not true 3.55 gears would get me out of the hole quiker and have more rpms through the traps.

i picked up more ET with a converter on my 2011 than i did doing a gear change. my 60' went from 2.0 to 1.7 too.
