best advice: tow it to a professional tuner mechanic that does ls engines all the time. I myself go to Tommy Wong at Wongs performance engineering in Vancouver, your in Texas with lots of performance shops and manufacturers...I would never attempt to tune my self with HP tuning being inexperienced I go to a pro with hundreds of library saved tunes, GM hard and software and load bearing Mustang dyno.....$$$$$ oh and a couple old electrical engineering degrees and a shop with a months long waiting list..... yours could be a fairly quick fix for a experienced pro but tuning...$550, a little mechanical work..maybe parts..dont know your set up if you Zl1 pump, twin or three pumps, BAP or what.....
