Bullitt tuning issue vortech

[Rockford]

Sorry for the repeat post. Also in FI section. Figured maybe boosted bullitt owners may have insight.

Hoping maybe someone has an idea what could be going on. My installer is having difficulty tuning my 2019 Bullitt. Basically they are having overfueling by almost 60%. They cant get correct AFR at idle. If they pull the maf tables by 60% it cleans up somewhat. It's a beefcake stage 2 V3 kit. It include the gt350 throttle body adapter plate and intake tube, ID1050x injectors, bap, and standard 3.6 pulley. They are in the process of swapping injector to rule out faulty injectors.
Mechanical timing, vacuum leak, and bap have been double checked. Next is getting a different tuning file.

My question is can the gt350 throttle body or gt350 intake manifold in the bullitt be causing tuning issues? The shop does many centri coyote jobs. They have never had this issue before.
Thanks.

Did it ever get worked out?

Had the car about 2 months now. Drives great as a daily. Very linear power band. Over 5k gets rowdy but at low rpm’s drives stock. Very happy with my decision. If the whipple wait wasn’t so long I would have probably gone that direction with my manual. But this is my first FI car and the vortech allows me to work on my shifts without putting the car in a ditch. Overall real happy. Hopefully the car will last a long time with this setup. Also did the steeda tri-ax shifters, great improvement over stock. That or mgw shifter should be a mandatory first mod

Is it just a street car or will you be racing it too?

Glad it got resolved. How much power did the vortech make?

It made 660 whp on pump 93 I’m going to take it to another shop to dyno again to see if it’s reproducible. Overall very happy. It’s just a daily street car although I’m planning on taking it to the 1/4 mile this fall.

Very nice number! I’m looking forward to hearing what it does at rhe track. Will you be on factory tires or stickies for the track outing?

Will be on nt555g2 and nt555r2 rears. I have zero experience racing so I’m just hoping to not embarrass myself.

beefcake stage 2 V3 kit, is that a Whipple? I googled and that's what came up. Nice numbers. You thinking about E85 in the future, to push deeply into the 700 plus HP range?
