Question for A-Train
I have a question for you...All the MSD crap has been taken out of the car. It was determined that the MSD box had a faulty channel, which was being amplified by the tach adapters and blowing the coil packs.
Now that all that crap is out of the car, I am using Jim's tune BLOWN, but the car starts to miss as I go to wide open throttle. I take my foot of the gas and hit the brake to lower the RPM's, then I depress the throttle and all is fine. I notice my A/F guage is in the lean side of stoich.
I switched with Jim's advice to the BLOWN3 option in the tuner which is a richer mixture and the car runs sweet at wide open throttle and like crap when under 2000 RPM's.....
Any suggestions? I am taking the car to my mechanic to get dyno'd tomorrow. He has a Dynopack and will also let me know the BLOWN and BLOWN3 A/F ratio's. He swears that there are no fouled plugs or bad wires, but with the car running on 6 of 8 cylinders for so long is that possible?
