chipping for a 6% increase isnt bad, that would be like us getting 113 hp at the crank for $100.
the cruze engine has been on my plate recently. the only issue i see is our access to only having the cruze passenger engine mount. the engine bolts to our tranny, the harness should (should) be the same unless us manufacturing changed anything. if you have all the sensors, harness, ecu to plug into the body harness (and pins match), that should be most of the swap. things like flywheel, clutch etc may or may not match.
this is the route ive been thinking about recently. with a trifecta tune you'll almost double the stock hp and torque.
