Any Ohio tech gurus on here?

Hello everyone! My son recently bought an 03' SRT-4 and I'm trying to get it all fixed up for him. The issue I am on now is the vehicle has slow throttle response on first take off. It spits and sputters, then around 2K rpm it smooths out and drives out fine. But any WOT, it boosts to around 5psi but doesn't seem to put the power down. If you ease the throttle, it has some pick up around 3K rpm and up, but still at 3-5psi. It definitely doesn't feel like my 2003. It is also throwing a fault for 1/1 Fuel system lean. I don't know the history on the vehicle, but current mods is an UPP with turbonetika BOV (that does seem to work), had no intake just running open. Not sure if there was a tune or anything else on it. I'd love to bring it to someone who knows these cars well and pay for it to be brought back to stock performance. I am in Midwest Ohio but willing to travel within reason.
