full power stumble - ZR-1 Net Registry Forums

In first when I have the power key on at around 5000rpm I have a stumble. Now in second I dont have a stumble at all. Now the gas is over a year old but I did add two cans of octane boost so I am going to run it out first and put fresh in to see if I have a fuel issue. I just replaced the pumps and I hope that isn't the issue cause man that was hard to get back in. I also checked the pumps and checked the check valves.
