does anyone have problems with surging at 85mph? If Im at WOT its fine. but just cruising it will surge and not go any further??? Fuel pressure at 20lbs. Any ideas....also stock turbo.

 

just me? ..........

 

Guess so


Sorry, havent had the same problem.

What EGTs are you seeing when it happens? or is there any fluctuation when it happens?

Also, is this with the programmers on? and what settings? Tried pulling them off and see if it still happens?

 

Can you describe exactly what she's doing when you say surging?

 

700* bddl on performance, quad xzt. It could be the bddl. I cant just take it off though and go drive 85mph to see if it will work. It shudders and will not go anymore kinda like its gasping for fuel but it has 20lbs.

 

Rail valve gone south maybe...?

 

well maybe I'll take the boxes off before assuming that.
