So... here is the short story, Had cams springs retainers, fuel pump, and injectors installed a dual map tune 92 octance and E-85 (Cobb AP i can switch back and fourth). So i got the car back once for two days and then it had to go back due to a bent valve spring, so they took it back and on the Dyno there are no issues runs like a champ! Off the Dyno, here is where where the issue comes up, on the road, the fuel pressure drops off, Right now it is still at English Racing (went there in August and still there) they are trying to diagnose the problem. Any thought on where it could be.... Not bashing English Racing, there customer service has been Stellar (with the exception of one person there). They have really worked well in helping my wife with this while i am on deployment. So any thoughts or what opinons on what might be going on.

 

If English Racing can't figure it out, not good.
Good luck with your repair, hopefully it will be sorted out.

 

YEA we are talking about maybe a surge tank

 

Have them check all fuel hoses, including the intank ones...particularly the fuel pump assembly feed hose that goes from the pump to the top of the housing. They crack/rupture. Could be explaining your low fuel pressure.

 

but only when i am below 1/4 tank/// they are saying i might need a surge tank
