Fuel pressure, 38psi no vac ?

RE: Fuel pressure, 38psi no vac ?
I am playing with my fuel pressure a bit to see if any adjustments make it run better / worse, trying to find my best option. I wanna take it down to stock pressure n work my way up slowly and find my hot spot, i believe 32 psi is stock pressure with vac. on, just double checking myself.

does it run bad or have any issues or just experimenting?? cause I see you have a tfs stage 1 cam in a 95 mustang ...sometimes they can cause idle issues as the ecm in the 94-95 is quite sensitive.

yeah I know..I did a tfs kit on a 94 not to long ago and the idle hunting was a little annoying but nothing a tune can't cure...if your not going to use a stand alone tuner.....SCT or Diablosport I believe are fairly decent tune programs burned Via a chip that 'll cure a lot of drivability issues with your set up if any exist

It seems like it runs best when the FP is at around 32 with vac on. But i dont wanna be running lean. Once its running it runs fine. When i start it, it surges up high, then drops down to around 500, surges back up, then down past 500 n stalls out......I know these damn computers suck for pretty much any cam.....I just dont have the money right now to take it to the tuner, but i know i can get alot more power out of it if i do......I know its not as strong as it can be, which bothers me. I guess i'll start saving my pennies.

h a ha ha ...I don't mean to laugh but what you just described was exactly what Happened when I installed the tfs kit h/c/i on a 94 .....you can perform a idle relearn and set / check the tps follow the instructions to the T.....this is only a bandaid fix and will still have some idle issues but for the most part it'll run okay until you get a tune.....The kid I did it for was out of money so he didn't get a tune as of yet but a tune will cure most of the idle issues..in recent days I've talked to alot of my tuner freinds who have more experience and capibilty to tune via chips and they told me no problem...been there done it!!! tHERE IS A CAM THAT'LL WORK GREAT FOR THE 94-95'S THAT WAS DESIGNED FOR those cars it is the STEEDA #19 cam and works well and gives a decent idle!!
