Well guys,my question is,did you feel a big difference swapping the j-tubes to the bigger 90mm?im thinking on getting one if they help much in power.now i dont think mine is a 90mm,its a 112 on my 08'4.8.
no wonder if magnuson has actually dynoed the difference.

some say the 90mm adds 35hp. I did the swap with a few other things so cannot tell you how much i gained. I think its a worth while mod expecially if trying to squeek every single hp.

The 90mm alone is probably worth a little hp like Bill says but if you combine that with meth, injectors, ect I think it just eliminates the bottleneck effect in your system. Sooner or latter it is going to need more air to make more power.
