I just recently installed a Weiand tunnel ram on my 454. Everything went together just nicely and after a simple few tweaks and some adjusting to the timing I was running just like before the old stuff was removed. I took it out to run and see how it performed and had some issues I do believe to squirter's being on the small side. I am running a single carb tunnel ram set up. When I used to go full throttle right out off the line it would take off like a rocket, get on plane and stay strong wide open with no hesitation with the Edelbrock Performer 2.0 set up that was on it.
Now when I stand on it it hiccups and coughs for a sec and as I back off it smooths out and runs consistent at 3/4 throttle but as I go to the floor it almost wants to die. I don't know Holleys that well but from what I have been told and what I read it need to increase the squirter sizes in increments of 3 according to Holley. I don't know what currently is in there now and haven't even begun to look into it. Is my assumptions correct on what I'm describing and assuming could be the culprit here? Any advise is greatly apprectiated!
