Need tuning advice on my GT

[Sonic_GT]

I have an 03 GT with the following mods:
JLT RAI
BBK intake elbow
O/R xpipe w pos flowmaster mufflers
FRPP 4.10 gears
Diablosport predator tuner w can tune

Basically used the tuner to accommodate for the gear change. Should I be looking into custom tunes or stick with the can tune? Not much has been done to the car and it has an automatic trans. Would there be a noticeable gain if I did get a custom tune? Thanks.

I think a canned tune would be fine. As always though, a custom tune will help the most.

If it was my car, I would keep the $450 and go with the canned tune. make sure it is from someone legit though
