We'll let you by this time, but never say CHIP again !
For the SRT6, there are many options that will increase horsepower and torque.
There are also many options that will improve handling and braking.
All it takes is $$$$$.
The MAIN options are :
1. a DCAI from NeedsWings.
2. A tune from EuroCharged.
3. a handling package from Ground Control.
4. various pulley combinations from a variety of sources to increase boost ( search the forum on this )
( the above from a non-SRT6 owner, just what I've read here. Some of you blower heads chime in please )
