Holley ecu dealers

[Syclone892]

I don't post on hear much, definitely a lurker I am planning on purchasing the Holley dominator soon and wanted to check pricing and see who is out there to help tune or at least give some support after the sale.
I have a gmc syclone with a turbo 4.3 v6, not too many stock parts left on it I lost my stock ecm tuner and feel this is my best shot at getting it running good and also the most reliable!
I've owned it for over 12 yrs and tore it apart shortly after buying it so I have never been able to truly enjoy it and now I want to get it so I can put some miles on it as I maybe putting it up for sale per the usual, married, really want to buy a house and we are expecting our first child in July

Thanks for the help in advance I really appreciate it
