This is why I said 95%. You're talking about the other 5%.JKTUNING wrote:The stock firmware also has it's own limitations which can make tuning a higher HP setup a little tricky. You end up with a good bit of lost resolution, for example transitioning from cruise to WOT at different RPM points. This is only when using an "NA" firmware on a boosted setup.. like you would be doing with a KA-T.8-bit wrote:95% of ka-t builds would shine with nistune.
Also, what wasn't mentioned here.... the stock ecu, which nistune uses, has algorithms for smoothing operation. That smooth driveability in cruise is hard to replicate in a standalone. My calum (like nistune) with my own street tune was more powerful and more smooth than a dyno tuned standalone, as vouched by Sean C (he bought it and replaced his standalone).
Sure you can work around it and everything will turn out ok but there are just little things that the community has lived with for so long that I guess it has just become standard tuning practice.
But alas, I will agree that a properly tuned stock ECU based vehicle will generally run better than most standalone systems. This is mainly because most people who are tuning the standalone aren't capable of dialing in all of the little things to help make the car drive and act like stock.
Have a look around you. Very few people pass 1bar(400hp).
