Bad Tune?

[Horizon5.0]

I have a 2019 Mustang GT A10 and i have kooks catless 1 7/8 long tubes, JLT open box cold air, and MBRP Race catback. I had my car custom tuned and i make 462-465 whp on e85, and 434-437 whp on 93. im being told this is pretty bad for my mods and i should be making a lot more. i talked to a guy with identical mods making 490+ whp on e85 and 460+ on 93. is my tune bad? if it is, who should i go with to get it fixed? is there a custom shop in south Florida that’s good or is a tune from a tuner like lund, tricky, or pbd good?

Maybe the dyno you used isnt as accurate or is more accurate than others? Was it a mustang dyno? What's it run at the track? It's just a number, are results good?

it was a mainline prohub. i did take it to an 1/8 track and best i ran was 8.38 at 92.6mph

Dynos read differently. 490 is pretty optimistic for that combo. What did you run stock? If you don't have that number it's really hard to judge the modified number

Those are good numbers with those mods.
My car has very similar mods as yours and made 473.
What was the temperature and DA outside that day? Was the hood down or up, was the car ran several times on the Dyno before making those numbers?
What gear did they use for the dyno pull?
Which type of dyno was used? All these things can dramatically change the numbers.
Also was your friends dyno using STD smoothing 5 or SAE?
