I just put a petris in my 94 it was 400 but for an extra 50 they give you a 5 year unlimited mile warranty which I thought was great. My car runs as good if not better than it did with the original opti. I didn't really want to spend that much but I'm willing to pay for reliability I like to take this car on long trips

Same here. But I skipped the extended warranty. I figured they would find a way to blame my install and void it anyway.
For a solid solution, $349 shipped isn't bad. Petris web site talks the talk, so my fingers are crossed. Too hard digging that thing out when it fails.
MSD touts that you can adjust timing on theirs, so you could advance timing and maybe make a little more power.
Anyone have any comments on that?
Only makes global adjustments. That's fine if the engine's timing is globally conservative (like on some older cars), but I don't think that is the case with the LT1.

You're pretty much dead on. My car started to develop a miss/buck a couple weeks ago and even threw an H16 Code. I tried to contact Petris Enterprises who I purchased my opti from 2 years ago (with the 5 year warranty) and it took 2 days for him to respond by email. I replied with my situation and I still haven't heard back. I think they are just going to blow me off since my problem is intermittent at the moment. I would personally go with the SacCity AIP Opti with the two year warranty or just go directly to AIP website and find the "2011 Series Optispark" With upgraded AIP encoder. Its $139.00 with a 90 day warranty. Same unit that Sac City sells.

Wow! Same price as an AC Delco cap and rotor!?! I'll consider this for the '95. Thanks!
...and then the PCM puts the timing back where it thinks it should be.
Ah...no, it doesn't. How would it accomplish that? The only info the ECM has with which to "think" is the info sent to it by the opti. There is no other crank or cam orientation input so the ECM can't possible "know" anything other than what the Opti tells it.
