My suggestion is you take your vehicle to an automotive service facility which specializes in classic automobiles and has knowledge regarding the conversion of a carburetor fuel system with an old-school EFI system before you blow up this engine. This is far, far out of your league. Bite the bullet, pay someone who knows what they're doing.

 

Greg's Auto Repair is located in East Nashville, it appears they get very good reviews & it looks like it's an old-school shop - might be worth a call. Good Luck.

EDIT: If you read/scroll down through their FB page, note they recently installed fuel injection on a 69 Firebird. At least this is a service facility which knows about EFI conversions.

 

i agree with your advice to the Op to take it somewhere as his knowledge is obviously limited.
HOWEVER don’t anoint someone “EFI experienced” because they post one conversion. I have over 15 years of EFI experience and training and I still learn something new all the time.

 

We both know in today's automotive industry most folks would be hard pressed to find anyone w/ knowledge of a classic engine EFI conversion; at least there's a better than none chance these guys have more than an inkling of knowledge compared to some service garages.

 

If it was running good than having problems at wide open throttle under load. It is probably the fuel filter. K.i.s.s.( Keep it simple stupid) over looking the simple stuff . If you did turn some of the adjustments it’s all good own up to it, and read the manual and start at factory settings.
