The object of this poll is to determine the baseline distribution of *STOCK* 405hp Z06 engines ONLY as delivered from GM for 2002 thru 2004 model years. Let's be conservative, and round down peak rwhp decimal #s, e.g. if your results falls within the range 355.01 to 359.99, then enter youf vote in "355-359".
PLEASE BE HONEST, and provide your Dynojet peak rwhp in SAE "corrected" units. If you have multiple dyno test results, post your best # only. This is NOT a poll for owners with internal engine mods, blowers, headers, or catless exhausts systems, etc, so please don't post unless you baselined your Z06 BEFORE you modded it.
If you dyno'd with only minor LS6 "bolt-ons", that's okay. Minor mods as considered aftermarket air intakes, filters, MAFTs, TBCB, and simple D-I-Y electronic tuning tweaks using LS1Edit, Predator, HPP+, L-TSTATs, are all okay, individually or in combination, but PLEASE no mods that require race gas!!!
What we are trying to establish here is a statistically derived "BASELINE" measurement of peak rwhp for the stock Z06 "as delivered" from GM.

Reason: Update to include 2004 model year.
Vararam and Stingers 359.2HP , 351.9 Same day as Alicia. Biggest difference was I was running rich and she was spot on. We had another car that day that had numbers in the 360's with good fuel trims as stock. All I can think of is variation in fuel injectors?
Anyway, tuning will help and getting a lower temp thermostat.
