had true duels put on recently 2.25 piping mandrel bent. headers, high flow cats, borla mufflers, x pipe, dumped after the axel. i am only getting a top % of 68 on a full load. why am i not getting a full 100% load. maybe restricted air flow? the only other thing i have is 4.10, cold air and the programmer.

4.6 4x4 97


any thoughts would be great!
thanks

 

guess i should maybe post this in the exhaust section?

 

Were you getting 100% load before your mods?

With your mods its a really good idea to get custom tunes to take advantage of them....

 

yeah i figured someone might say that i never though to pay attention to it untill my work truck was put on a scanner and not getting %100. guess its time to get the gryphon?

dont think that it could be the 2.25 pipe choking it out?

thanks for the input
