Lol... come on Clap. Some of the comparative results posted on Cobb's database are questionable at best. I recall there being two cars racing each other on video showing very different results than what were shown on the dyno.

Stage 1 went 112 on my car. People on here have went as high as 114 on stage 1. Stage 2 on my car will go 114-115 based on the butt dyno, some will go faster, esp the auto guys. Like usual ill post the results. |

Both are nice to your transmission. 6AT issues only start to be an issue at much higher power levels (upgraded turbos running 18+psi of boost). |

As far as numbers being fudged with, why would cobb post up all these results, its only a matter of time before people starting hitting personal dyno days. If numbers dont match up, they just burned them selves. Only an idiot would do something like that. |

Looking forward to it. Trapping 114-115 on pump gas with no meth is impressive.

My buddy barely made 330 or so whp on it and 370 wtq or so. And his car pulls very very hard. Harder than mine if I dare say it. His trap speeds are all much higher than mine, even if our E/T's are the same. This is not to add to any tuner wars, but rather to point out that COBB's dyno does not read high. |

From Cobb:
Stock Vs Procede (no mods) 67 Delta Stock Vs Cobb Stage 1 (no mods) 73 Delta Stock Vs Giac Stage 1 (no mods) 71 Delta We can see the majority are in the same ball park on stage 1 and stock. So looking at peak numbers there is no differnece, atleast not on stage 1. You also need to look at the power under the curve and realize there might be some underyling factors here like heat soak. Also the dynos definitely do not read high. With baselines of 240 they are on the low side. Realistically you can put this car to dyno 270-280WHP stock. |

I understand cobb can monitor each cylinder's ignition advance, but can they adjust the timing for each cylinder as well? Because that is huge compared to piggies which from what it seems can only monitor one cylinder, and can make a big difference in consistency.

When every other tuner's dyno on stage 1 makes 340-350WHP they only made 310-315WHP on Cobb's dyno. |

Based on those 3 the power under the curve goes to cobb so far. Looks like that boost down low with proper timing works after all. |

And perhaps the dynojet read low? Who knows? If COBB's dyno reads high then you are claming that a car making barely more than stock power is trapping approximately 113 in the quarter? |

There are a couple Jb4 but I think something is not right as the deltas were 40WHP from stock to map 1. If they are in fact right someone else can post them. I dont want to be shot at for being the messenger of poor dynos LOL

People need to stop referring to cobb like they do to piggy backs. It is a stock ecu that is reflashed to run different parameters. It still works on the stock ecu logic just like a stock car, but faster.
A piggy back tells the ecu its running stock and alters certain parameters to its best ability while the ecu doesnt see any of it. |
