Hey guys just installed my Brenspeed custom tune 20 minutes ago, took her for a run and its alot more responsive, especially low end kick down. The engine responds much better after a shift of gears. It practically jumps forward during the exchange. Before it would almost bog 2 to 3rd gear. My set up is stock cold air with k&n drop in filter boom tubes, an Eibach pro lowering kit with a Eibach swaybar kit. I also have American muscle gt premium wheels, and new Bridgstone pole position summer tires....My next mod is an aluminum drive shaft. Stay tuned!!!

 

I have the 93 octane tune from Brenspeed also. You most likely picked up another 15hp with your already potent CAI. You are getting the mod bug and it never stops.

 

My Brenspeed 91 tune is awesome, love the new power

 

Has anyone here measured the hp increase with this upgrade?

 

I know when you add a aftermarket CAI and tune to a 05-09 you can gain anywhere from 20-25 rwhp. So with your already stock CAI you should gain 10-15 hp. You can always ask Brenspeed im sure they have tested their tune with the stock CAI.

 

I don't remember the source, but I am 99% sure that it has been proven that the CAI is mostly hype as far as purported hp increases. Almost all the power gain from the tune/CAI is from the tune itself.
