OVERVIEW:
GM High-Tech Performance (GMHTP) was originally published by CSK Publishing in Saddle Brook, New Jersey. It is a re-titling of
CSK's High-Tech Performance. The re-titled magazine focused content on post-1985 electronic fuel injected GM performance automobiles
including Camaros, Corvettes, Grand Nationals and Firebirds. Strong technical and how-to articles addressed EFI, suspension and body
modifications, supercharging, nitrous systems, turbo technology and engine management systems.
The origin of this title began with High-Tech Performance. In 1993, a group of CSK staffers - including Johnny Hunkins, Jim Resnick, D. Randy Riggs and Jim Campisano - decided to create a car magazine about late model fuel-injected muscle cars. These newer cars were fun to drive and provided great value for the performance. Originally wanting to cover EFI vehicles from all manufacturers, this dream was short-lived.
Many magazines were being consolidated under two major players - Primedia and the former Petersen Publishing empire which had become EMAP-Petersen. With this consolidation came a situation where each publisher had multiple titles covering the same vehicles or target readership. Some magazines disappeared, but other publishers chose to focus more carefully. So in late 1998, GMHTP shifted primarily to cars from Chevrolet and Buick since Ford and Chrysler vehicles were well covered in other titles.
OWNERSHIP:
The editors and staff rode a wave of changes as the title moved through various new owners:
- 1997 -- All CSK titles are sold to McMullen-Argus, a division of Primedia,
- 2007 -- Primedia sells its Enthusiast Media division including former CSK titles to Source Interlink Media for $1.2 billion, and,
- 2014 -- Source Interlink rebrands to TEN: The Enthusiast Network, and multiple titles are ended including GMHTP.
When GMHTP ended print production, it was folded into Super Chevy, and subscribers to GMHTP got Super Chevy in its place.
