What does anybody know about the Holtzman Compensation Units? They seem like a good idea, btu I was wondering if they work good and are worth it. I have a 2000 ZRT800, piped, clutched, breatehr box. Thanks

I am getting ready to purchase one for my F III 8. I have heard nothing but good about them. We let my buddys mod xc 8 idle for 5 min in 35 degree weather and not a fouled plug. That was enough to sell me. By the way. this sled is jetted for negative 20 like they recommend.

shouldnt have any effect on the idle, works from 1/8 throttle and up. I have had it for 2 years and over 3000 miles. Need to set it up correctly, including mid range etc.
