Did you weigh the stock parts and compared to the weight of the GPI parts?
Would be interesting to know if the weights are actually the same, which would then really mean that no balancing is necessary.
How many miles on the motor since the build?
What kind of max WHP/TQ are you running and on which tune?
Octane?
Did you also upgrade the fuel system to LT4 parts?
