hey guys im going to be the proud owner of a 93 Z28. i was wondering who doies mail order PCM's for my car? im planning on a LT4 conversion...

 

I'm not sure but don't the 93's need the chip replaced while 94 and up can be tuned with a laptop?

Anyway, www.lt1pcmtuning.com is awesome and be prepared to be educated about the cost/benefit of LT4 vs aftermarket

Before you ask the next obvious question about LT4, use the SEARCH function as the topic is a dead horse that has been beaten to death. Remember, that 93 is 18 years old so chances are every "generic" question such as LT4 has already been asked

 

are you looking for a ecu or a tune? 93 has a memcal in the prom that can be tuned or you can get a addon that takes the place of the memcal. look like this. blue part is the memcal, green part is the tune.
i am using a tune from solomon at the link provided by tig. great guy and easy to work with. pcmforless is a good place as well but a little more money.

 

Thanks guys!
