this # will vary between cars, based on a variety of factors such as what mods you have - i.e. some chips make more boost than others in the upper RPMs, and MAF flow is directly related. And then there are exhausts, and even the intake manifold design has varied between years (luckily you have the better one!) So you can't compare #'s between cars to single out one variable (the airbox), but it would be interesting to put this intake on your car and then see the result.

By the way I'm guessing you did this in 4th gear (based on delta time). Perhaps at those 100+mph speeds you may get some pressurized effect at the snorkel which will increase the #? It would be interesting for you to try 3rd gear to see if you still get as high as a reading.

I've even heard of an XR chip owner hitting 290, don't know what the weather was, but again this is simply a function of the mad boost that chip has. Most chipped cars put out 250-270.
