Holley sniper failure, this time its all bad.

Funny ( but not laughing) I installed a Fuel injection system on a small block for a $50k resto mod going thru my shop.
It wont hold the tune and FI Tech seems to not care since its paid for. What little help I get has been like I was asking the Queen for part of her sandwich.
I was looking to the Holley as a replacement because the client wants the car now and it does not start right and all is with in specs.
I feel your pain brother.
Chin up and it can only get better!
