When I got my Rocket there was plenty of decel popping but I liked it.
Was running after market Thunderpipes and stock air in take. Got a set of Ramair intake a tune from sleeves and popping reduce.
Had a bit of trouble with idling so got new fuel filter and another tune loaded in the shop.
Turned out it was dirty spade terminals cleaned and die-electrical grease fixed it.
But no decel pop now.
