    Just my oppinion I've used the Hypertech thermo chip which is the 3rd or series III power chip offered for my 60* tdc v6. Had excellent results in combo with an updated late model performance ecm and power you could actually feel. It required the 160* thermostat as well. Seems to be perfect for the old style obd ecms. However I've heard really mixed results when Hypertech chips have been used on newer ecm's. I found (for me) keeping all three in my personal stock gave me a couple choices in tunning my old tdc. I think it's more of a matter of finding the right combination of bolt on mods suited to running Hypertech chips for the best results. I like them just fine but that's my oppinion and what worked good for me. As for spark plus I use the delco Iridium plugs in all my rides. Their about $6+ per plug.

    The "new style" plugs (Iridium, Platinum) are basically much more durable plugs. So whereas you can get 20K-30K miles out of copper plugs, you can get 60K-100K from platinum and Iridium plugs.

    Chances are you won't notice any immediate performance difference going from regular plugs to Iridium plugs. But over the course of the plugs life, you will notice more consistant performance and better fuel efficiency, since Iridium doesn't degrade the way copper does as you put on miles. By the time you change copper plugs, you can have enough gap erosion to cause a misfire. Iridium has been proven to show little to no gap erosion even at 100K mile change intervals.

    To put this in perspective, I changed the plugs in my car at around 80K miles. I was getting a slight misfire under throttle at lower RPM's, and the plugs were original (AC Delco Platinum) so I decided to change them. Sure enough, the plugs were worn and the gap was eroded enough to be above the .060 OEM spec. Still very impressive for the plugs being 10 years old and having 80K miles on them. Now had they been copper plugs, they would have been completely worn out in about half that time. Had they been Iridiums, they would probably still be going strong today with 92K miles on the car.

    Best thing you can do is ground your block. Run a 1 or 0 gauge wire from the block to a solid ground. Other than that you can use a blow torch versus a spark plug and it really doesnt make any difference in a properly tuned car. Most "gains" are from plugs compensating for a improperly tuned car to begin with. Ground your block boys and girls. From the factory they have a piss ant lil ground that isnt worth a damn.

    No leave the ground on the back and ground from the front of one of the heads as LSX motors have "spare" threaded holes there.
