Hi everyone, just installing a new cam into my ls1 223/228 @.050 .580.588 and ground on a 114 LSA, once i close my engine up would it be safe to do my initial start up on the old tune that was running maffless and what parts of the tune should i focus on ajusting first and what are the normal things that need looking at with this type of upgrade. I do understand that i will have more of an idea once i fire it up and at this stage it might be hard to help me out. I have a V1 with a PLX WB02 setup that i purchased about 2 years ago. Done a little tuning with it and found it great. Any help would be awsome as i am new to the EFILIVE world of tuning.
