There will always be, and peoples will always find another way to make more power regardless of not being able to put an actual header. The biggest restriction for us current LLT is tuning.
2012 LFX will not be short in this department with the new delphi ECU and E85 capability. Plus our only current tuner and other companies are already working on a tune for this new LFX.
There will be alot of possibility with this new e85 fuel flex LFX. Especially when someone throw boost to it.
