K 94 Camaro LT1

Vortech Supercharger, MSD 6BTM box. All bolt ons

Now problem:

1st gear...when it hits like 3,500RPM it sounds like its bouncing off the rev limiter, but its only at 3,500. Its like bah bah bahhh bah bah. Alot of hesitation

Could this be an opti??

 

Some info please? Is this a new install or is the install old and the problem new?
You do have proper tuning,and fuel system upgrades?

 

Sounds like detonation to me. If that's the case, you may be damaging your pistons.
