well i installed my jammer 5 nozzles and wow what a difference. for those who are wondering i did the nozzles myself goes easy take longer putting the injectors in the doing the nozzles. anyways wow these things make a difference may truck has a little lope now but i think that the hot rod vp. the only thing is im having a starting problem after the truck sits. is this bad orings again like it was the last time i had this problem or is this something to do w/ the injectors. the install went pretty smooth except for #5 wich did not wanna go it at all. ended up forcing it in(i know not good but... ). anyways these things really make the truck scoot and smoke wow w/ the big pump a slow turbo and these babies oh man i can smoke. :-lafOo. :-lafOo. :-laf.
