Holley 4150

[kenhaw]

I have an irritating problem

My mods are as follows.

Chevy 350 Fastburn w/hot cam kit

Procharger F1, Carb Shop Holley 4150

My problem is that the engine stalls when I brake hard.

I have jet extensions on the secondary jets ( installed by the Carb Shop)
I also tried to install the same on the primary jets, but no luck so I will remove those again.

Any ideas? This is not only irritating but also dangerous to drive with.

Thx in advance

Kenneth
