Will a '93 LT1 benefit from a AFPR since the PCM will not make adjustments? If so, any recommendations on an AFPR?

 

Yes, it will. Hypertech sells one for about $139.95. It's a direct replacement. The cheaper one are simply a part which gets installed into the stock unit. Not worth the trouble.

Expect about a 10 RWHP increase. You should tune it on a dyno to get the best results.

 

I would highly suggest picking one up. I installed a Hypertech AFPR on my car and picked up 10 rwhp and 17 rwtq. Wow they cost 139.00 now? I picked mine up for 90.00 a few years back.

 

SLP sells one for $65, anyone tried this one?

 

Anyone?
