e fuel pressure spike

[earlybroncoboy]

hey guys noticed tonight while shifting in hot tune rippin on it i get a huge fuel pressure spike like 90-100 psi when im shifting gears. I'm running dual SD pump with an aeromotive reg. Any others experience this issue. i don't want to pop an o-ring.
thanks

What regulator do you have?

13109 - A1000-6 Injected Bypass Regulator Aeromotive. not even 6 months old. and i do'nt have the boost tube hooked its set at 65 psi.

What do you have for a fuel pressure gauge? I had the same regulator and once I was cruising down the highway and noticed my pressure go from 60 to pegged past 100. I pulled over and after my heart settled down went to check things out. Turns out nothing was wrong but a failed sensor for the gauge! Just something else for you to check out.

i have a glow shift. night not be the best quality. but its like its calling for demand at wide open then when i let of to shift its not compensating fast enough. maybe my return lines aren't big enough. i will run it again tonight and see if it continues. I heard this was a good regulator one of the best that is why i bought it.

Glowshift would be my first suspect, those gauges are horrible. At least once a week someone is calling asking if we service them because they stopped working, they look cool but doesn't help if they don't work. IMO Autometer or Isspro.
