Have you seen the people talking about it frying their ecus? How do I avoid that. And with mine being carb the only thing I'd need it for is the speedometer adjustment and trans functions with my 2400rpm stall converter and corvette servo
So I just dropped a new 383 in my 97 k1500 with 37s and installed 5.13s. Now my speedometer is all over the place!!!! How can I fix this..... please help.
