You know what? I think a lot of people are way too picky about dyno's. I can understand that there is a little difference in days done etc, but still. It's a good basline. I know the Renesis has incredible output for its size and everything, but still, dynos are pretty self evident.

I don't really trust vendor dynos. They have too much to gain for putting out higher numbers. A few of the things I bought, the vendor dynos said one thing, and they always registered drastically lower. I trust posters on this board, but when a product gets several dynos by people on the board so much the better. RX Tuner & Polak have much better methods of dynoing product. On several of their tests they literally leave the car in the same position on the dyno vs. some of these other vendor dynos where you notice that the seperate dynos were performed 6 months apart in completely different conditions & were not normalized/standardized.

been there done that. I did like that side affect (less carbon)with my cz unit. Unfortunaly I didnt know enough about tuning to get the thing to work the way I wanted on the track--so I sold it. I still think in the hands of a knowledgable person it can be made to work well. 13.2 is nice and conservative but will get you some gains--good work

Nemesis was already in the 190's from his previous mods. So getting 200+ whp from even just his CZ & tuning would be easyily understandable. With some of the other cars, the CZ was delivering 12-25 whp with just the unit itself.

Nemesis, good job. Congratulations on getting over the 200 whp hump NA.
