I don't know how you see a gain when it will retard the timing.

2 reviews are on here with this mod (or similar). one with the SL55 pipes and Y Pipe the other with the SL55 Y pipe but std intake pipes (which are very restrictive). The latter one was not tersted at WOT and didnt go above 5500rpm and showed a loss. The other was tested using a G -Tech and tested with and without the whole mod and showed good gains. Also the Needswings CAI probably flows even more air than this mod and the ECU copes just fine with that.
What I can tell you is thay between 5,000 & 6,000 rpm there is a definate improvement over stock that you can feel. It also makes the gearchanges stronger. BrianBrave has even included the airboxes and air feed tubes (from the SL55) so would flow even more air and I can assure you he would not say it went better if it didn't... no offence BrianBrave but I know you take some convincing to be impressed.
