11mm pump character?!

Definitly LDA id say, once thst torx is wound out on top of ufo you wont ever need to touch that and then its all adjustments with pin and star wheel inside LDA housing, getting the right setting can take much adjustment, i had a problem where the power curve on dyno would drop mid revs and was a default with a custom pin getting stuck because it wasnt hardened enough changed to ground stock pin and solved problem its suprising how much the LDA can affect setup, there are more mods pump relating to LDA
