Re: Hypertech Thermomaster Chip for sale (2.8L, 5sp)
Hmmm, I went back to where I purchased the Holley TBI and the Hypertech chip recently and discovered that under the Holley TBI it states "Compatible only with stock GM electronics." [img]/wwwthreads_images/icons/crazy.gif[/img] This was not there when I made the purchase. Also, their tech said they were compatible on the phone [img]/wwwthreads_images/icons/laugh.gif[/img]. A lesson learned-not to just accept the word from an inappropriate authority [img]/wwwthreads_images/icons/mad.gif[/img]. I have emailed them this, and I am awaiting a response.
