Amazing Results after Haibeck work on my 90 - ZR-1 Net Registry Forums

Jim Stanley · 02-27-2019

Yesterday the weather finally was good enough to take my 90 Z for a spin after getting it back from Marc Haibeck. It is hard to describe how much stronger, smoother and quieter the car is. I had it shipped to Marc to fix a miss and several minor things. He was very thorough finding many things I didn't expect, such as a missing secondary fuel pump relay! The first time I nailed it from a rolling start, I felt like it was going to pop a wheelie! The performance change is dramatic! Additionally creature comforts such as repair of CD player, speaker amplifier, lumbar bladders, several lights, power antenna, etc. were expertly repaired. Marc also installed a performance chip AYBKG5. I'm sure that was partly responsible for the greatly improved performance, although hard to tell since there was so much else going on.

I would like to briefly share what I have been through since buying the car two years ago. Living in the Kansas City, MO area I did my best to get work done locally. Some was good and some was a total rip-off. Contact me off-post for details. If you are reluctant to ship your car to Chicago, let me say that I would have saved thousands and enjoyed the capabilities of the great ZR-1 much earlier had I sent it to Haibeck Automotive Technology first!
