Haibeck Chip burned specific for my car during dyno-tuning.

Just installed Haibeck yesterday. Incredible improvement over the 1st generation 91 OEM calibration. Worth every penny.
Mine is slightly modified to maintain low power mode standard on startup - because it's such a cool feature [emoji106]

my 91' z had its chip modified by john lingenfelter, anyways his shop did, when they did the 530hp package. this past year i had marc haibeck perform his magic to it.

I had Marc pull my DRM chip and tune my Z on the dyno with his. Here is a link to the video I posted on YouTube https://www.youtube.com/watch?v=UxGPzj1KUuk

My 1991 is a Corey Henderson 368ci build. I have suspected serious tuning issues ever since I bought it in 2020. Made the trip from Nashville to Chicago to get it to Marc and after taking some 02 readings confirming it was rich at the lower end and down on power (too lean) at the upper end and verifying good fuel pressure we took a look at the programming and confirmed exactly what I suspected and even found the root cause of a stumble at 5500rpm that I had noticed.
Haibeck completely reprogrammed and tested multiple runs and the wide band O2 readings are great now all throughout the range. Idle is so good now that you can hardly hear the aluminum flywheel rattle anymore. Very smooth.
Looking forward to making a few passes at Beach Bend in May. Will report back compared to last time I was there. I expect to pickup 4-5mph vs previous time.
If that proves out I will officially declare Marc the best tuning wizard for the LT5. As it stands drivability is as good as my stock C6 Z06 LS7 powered car.

This is the chip that is installed in my 1993, #135. It was installed by someone other than the person I purchased the car from. I do not have the history for my car from owners prior to the person I purchased the car from. It also has headers, no cats, x-pipe and Borla mufflers, relocated MAT sensor, K&N air filter, open air filter cover, Jerrys Gaskets air coupler, and 4:10 gears. The runs good.
