My 05 LLY runs great but while at idle starts surging once it’s warmed up to temp. Also when it starts surging the balance rates zero out. No injector knock or other noises just sounds like it’s cammed. Has new FPR Anyone had this issue?



05 LLY studded, deleted, FASS 165, PPE tunes, down pipe, 4” straight piped,

Cleaned MAF when I changed the filter last month. New MAP. No codes stored. Still has factory filter head but with FASS filter delete.
