Default throttle response

whats up im runnin a 92 camaro with 5.3 swap and ls6 intake still working some bugs out trying to get it to go closed loop so i can do some efi live tuning. Anyways what can i do to get some better throttle response outta the engine? Ive got a cai and exhaust on the way, would like some input maybe on the tuning side to make it real snappy when i hit the throttle.

Focus on getting the PCM into closed loop mode first, it's probably running in gimp mode using the low-octane spark table which would account for weak throttle response.

Once you get that done, there's usually plenty of gain to be had from both the high-octane spark table and the PE vs. RPM table. See the Tuning forum here for more detail.

You need to get the speed density tables dialed in once everything else is right. Make worlds of difference in throttle response.
