If you have access to a chassis dyno (Dynojet et al), that would give you a direct indication of how much power your car is making across the entire RPM range. For a bone stock 405 car, you should expect somewhere around 340 to 360 RWHP @ 6000 RPM. Around 210 to 215 @ 3000 RPM.

The stock PROM should have a blue plastic cover. If you look thru one of the holes in the top of the cover, you should be able to see a four letter code, e g. BMCB (stock '93), that will tell you what version you have.

If you'd like your ZR-1 to keep up with your C6 ZO6, that problem can be easily remedied by one of the engine builders here on the forum! [emoji6]
