Light Throttle Surging
I have installed 60lb Siemens injectors using the GB DVD and Data and im getting a surge as i go from 0-3-4% throttle. its like it bogs down. what might be the cause??? i have turned of DFCO as was suggested and no change. I have just changed my plugs too and nothing. what might be the issue?
Thanks

Anyone got a thought? could it be my pulse adder? what could I log to find out the cause?
Thanks

Not sure what to log. List me some PIDS and ill post a log.
I'm assuming Spark, AFR, Injector, What are the follower PIDS? and I head about a BURST KNOCK???

Sounds like throttle cracker/follower problem...
