and this was the same car, post 1.06 (admittedly, the pre dyno was before a borla header and an overpipe was installed, but there are numerous other examples out there showing similar results)
This fully supports my assertion that the Vortech kits were putting out similar numbers when they were first released (w/ new compressors even) as the Innovate kits are producing now. After seeing this, I'm not sure how you can say the tuners haven't unlocked the potential of the kit.
Again, i'm not bashing the vortech kit in any way. It's a great kit by all reports. I'm just saying comparing the vortech kit where tuners have had months to figure out how to extract the most power out of it, to the relatively new Innovate kit deserves some perspective. |
I based my statement off of dynos showing ~250whp when I ordered my kit earlier this year.... it seems some people were dynoing lower than that, but it should not take months to figure out how to extract huge jumps in power unless the tune was flawed to begin with
If two tunes are compared and one is higher than the other, I wouldn't say that tune unlocked more power... I would say the low power tune was just crap/not well tuned
There is a method behind tuning cars, when I was tuning I would lock the cams at set amounts of advance/retard... lets say 0/10/20/30/40/50 degrees. I would tune each cam angle, and then overlay the dyno graphs to see which came angles made power where. I have grossly oversimplified it, but if you have 5 tuners and they each tune the same car... I would expect their end results to be very close. Its not magic... one tuner does not have some magical knowledge or supreme insight that allows them to get more power vs a different tuner....
It also comes down to experience. Some tuners may be able to get better crusing mileage because they know that certain cam angles are just more efficient when at cruise. I will say that I have 2 tunes from different vendors, and they are vastly different in terms of power/fuel economy...
In the end, I don't think tuners are "finding" power in the kit, its just that the tunes are more mature and refined
