    2.6 inch pulley and tune = detonation

    my truck came with a 2.6 inch diameter pulley and an SCT tuner. When I get on it and hit WOT theres slight detonation. Ordered 3 custom tunes from Troyer Performance for $350. Should get rid of the detonation. Ill post the results once im emailed the tunes and get them downloaded to the truck.
