;A lot of people had problems with the chip and the injectors that
Howell uses.
It has recently been found that the Howell system is set as shipped to
15 psi.

The injectors that Howell uses on the recent kits are Holley 522-43.

A Holley tech man told me that they are rated at 60 pounds per hour at
13 psi and you would have to run at 21 psi to get 85 PPH flow.

The 454 truck that GM made with TBI had two 85 PPH injectors at 13 psi.;

So, if Howell is shipping the kits set to 15 psi there is no way to
get good performance unless you increase the fuel pressure.

That may be part of your problem

That system at 15 psi was designed for a 350 cu in. engine, not a 455.
