What was the DA when you dynoed?

hesham do you have your dyno graph? the old one and the latest,maybe it would be understandable if you show it.

hesham

no but i can get it tommoro i will change the MSDs and return the stock coils

i have a 280 PSI fuel pump and 30# injectors my timing is around 23#
and i can't go higher becouse i will have konck.

my A/R ratio is aroun 13.2 its not that lean but i dont know it is the problem

hesham

i found my problem it was the MSDs coils i will post my dayno with the MSDs and after i removed them

and when i finish my tune i will post my final results

hesham
