DLD1989

Hi, I'm Denny Doyle & live near Pittsburgh, PA. I presently have 7 Corvettes, ranging from a 1966 427 to a 2014 Z51. I recently purchased a 1991 ZR1 and need some help in understanding how the optional engine power switch / key works. When I start the car the engine power key light for normal is on, then when I turn it to Full Power after the engine temperature is normal, I don't notice any difference in how it runs, the engine and exhaust sound the same, before and after I turn the key to Full Power. My concern is whether or not the full power engine option feature is working. If it makes more sense to discuss this on the phone my number is 724-989-2688.

I don't know a great deal about how to participate in a forum, hope my message makes sense & am looking forward to learning more about forums.


Thanks,

Denny
