What gains should I expect to see on a pure stock ZR1 with a haibeck chip?

It will be by far the best bang for the buck that you can spend.
HP, a little. My super-sensitive calibrated seat-o-pants portable dyno says maybe 10-15hp but not more than 20. What you will get is a rock solid idle at 600rpms at the stoplight (barring any vacuum leaks of course). No CAGS. Better throttle response, instant 375hp (providing that everything else is working correctly), which equates to tire spin in 1st and 2nd by throttle only.

One of the first things I did to mine. Night and day change. More power, better throttle response, the car feels completely different. Smoother but with more power.

Marc does a great job. He dyno tuned my 93 @ BG and we ended up with 366rwhp. The car is entirely stock, turned out to be 427 crank so about a 22 hp gain.
He told me to expect 10-15... But for me, the other items is worth as much as the hp gains... Cheers, Ron
