Default Best computer chip for 94 Blazer w/5.7 Vortec

Guys, I think i need to get a new chip or reprogram my existing chip.

I have a 99 5.7 block with vortec heads and the GM TBI to Vortec manifold, cam is Edelbrock Performer with duration at 204 intake 214 exh, Lift is .425 intake and .448 exh with 1.52 roller tip rockers.

for a slightly modifed motor, who makes the best computer chip or can reprogram mine?
