Lets take a holistic look at the time frame.
They have to send out and get back the parts from the PowderCoater. Time frame unknown
reassemble all the parts on CF1. Time frame unknown
Figure out how to Dyno and tune the Crossfire. Time frame unknown
then they have too find someone to give up their car for CF2.. For a time frame unknown
then they have to go through the process of fitting and powder coating and getting it to run all over again. Time frame unknown.
Then they have to make the kits and they have to send them out to be PowderCoated and packaged before they can ship them out to the customer. Time frame unknown
This is providing we can keep Corky healthy, it does not get too hot in Texas, no one screws off to get engaged, no oil pump goes missing,the cash flow remains consistent, no bread and butter jobs bump us to the back burner to collect dust. no one quits,..at this point I can only concur with your statements of four years.
It seems that there is a bit of a pattern when we get disgruntled, then comes a update with pictures or a bogus update of 10 to 15 days to completion. Pacification just doesn't carry the punch it used to, less people chasing the carrot on the stick.
Back on the soapbox once again.
