I guess I am just confused why none of the other tunes ever hit that including procede. In 7 years they didn't learn what was ok to run on a stock car? How/when did Shiv realize 18psi is fine? Will procede now hit 18psi on a stock N54? Don't get me wrong I am all for this as it means I can crank up my boost. I just want to be safe. Last edited by Torgus; 07-18-2013 at 02:07 PM.. |

This Xpsi is "too high" argument is pretty simplistic and should be abandoned if you are here to learn about tuning. Boost is just one ingredient to the power recipe. Two others (ign advance and fuel) that play an equally big roll. But I suppose it's the most fun one to talk about because it is associated with cool things like turbos and bypass valves. As for other tunes not running 18psi, the piggybacks can't due to limitations mentioned above. The Cobb tune have indeed attempt this before but didn't seem to have solid enough boost/throttle control to pull it of successfully. In fact, they were running more than 18psi. And for a larger part of the RPM band. |

focusing on how much boost a specific tune runs is like focusing on what color 335i to buy. obviously, there are more options, packages, transmission choices, etc. that are equally important (if not more important). |

Shiv when will you have 93 octane? You should get alot more orders if the results are better which they should be. |

piggy backs can't hit 18psi in the lower rpm band without a backend flash. is it really that difficult to understand?

It's also worth noting that our OpenFlash tunes do not target peak boost in the low end (2000-3500rpm) as other flash tunes tend to do. There is also a reason for this. And it appears that others will make up their own reasons for that. Which is fine. You guys keep complaining and the rest of us will enjoy our cars. |

Shiv's tune is adjusting for everything even the engine. Your getting lots of hp with high boost upto 4000rpms then as the engine picks up and creates more power on its own the tune adjusts the boost to bring it back down to keep the power level the same. If they kept the boost the same the turbo would create extreme temps, and eventually would break. The reliability of the engine and turbo's would diminish greatly so there is no reason to keep the boost up past the turbochargers capabilities. If you upgraded your turbo's with ones that were efficient above 500+hp and 20+ psi, then you can freely tune your car to 20psi as long as you have the fuel and spark to do so. This is why people who use e85 and meth get more hp. They decrease nock and intake temps so they can increase timing. There still not increasing boost. The turbo chargers are done at a certain point and thats why they are tuned that way. |

For those that are unaware, running more boost down low produces more torque, so yes you will see a big increase in torque with 18psi down low. With this OpenFlashTablet map, Shiv is running more boost down low than the Procede piggyback, with the setup he's referring to when he talks about peak power between the two. Regarding the green highlighted text, what kind of load are you targeting in this RPM range on this map for stock hardware on 91 octane? I'm curious to know the reasoning behind it as well. It's just much easier for me to deal with facts and hard data, rather than making statements without it. |

I personally don't really see how blow off valves, a topic generally associated with novices and noobs are related to what the community sees as a safe pressure to run. If there are other variables that play an effect on the limits of this one variable that most of us are familiar with, which is pressure, then a simple explanation is sufficient.

Do you think it makes more sense to compare Protune maps with Off the shelf maps? Protune maps are extra $. Moreover, they are custom tuned to the car. Its totally different and unfair. For me, it makes more sense to compare free of charge, off the shelf maps against each other. Also, comparing different custom tunes at extra charge against each other makes sense to me. I don't agree that having an access to same tables means that the numbers are the same. Now you have the access to the same tables, so your tune would have the same numbers as Shiv's or PTF's? I don't have any idea of your tuning capabilities, and you might not have either but considering the in practice infinite number of possible combinations you can enter the values in the tables, there is no chance that the values would be the same for all of you three tuners. There will be a difference in how the car is tuned by someone who has been tuning cars for his full professional life and with someone who decides last year, that he can tune cars in the evenings after work and get some additional income. Basically, having the same boost, ignition advance and fueling results in the same performance. But the only way to have exactly the same boost, ignition and fueling across the whole rev range in all the ambient circumstances is impossible by any other means than copying all the figures from all of the tables from one tune to another. That is called copying though, not tuning. |
