ok so yesterday i was on my way home from work, and i did a second gear pull and around 5800 to 6200 rpms my car just cuts out. so i checked it in first second and third again, and it does it in all three. any ideas on what this could be? could it be spark plugs? mods in my sig

 

does it hit a wall or break up(like backfires?)

 

just hits a wall

 

It seems like your hitting the fuel cut, I am not sure what causes that tho.

 

Do you still have the stock intake snorkle to ram air under hood?

 

no i have a k &n cone

 

whats your boost limit set to in ecu flash? You may be hitting the fuel /boost cut due to excessed air passed what was set in the ecu. I believe stock is around 255, if increased air flow is reached at a certain rpm point it will hit a wall.(sucky feeling)

 

i dont really know what it is. i bought the car three weeks ago and it already had all the mods on it. but it just started doing it yesterday

check the coil packs and plugs it could be ignition

 

To check boost cut, dial back the boost a few psi, maybe to 20-21 range and see if the car still hits the wall.

yeah. Definitely sounds like a boost cut issue, what state if different did you get the car from? May be an altitude issue.

Like someone said b4, dial the boost back a couple turns and see if you still hit the wall

 

alright ill try that... the car came from tennessee

 

Ouch, not a great idea buying a car with mods like that, especially when it has horrible ricer springs like that. I would be surprised if that car didn't become a huge money pit over the next 6-12 months.

Anyway, it sounds like fuel cut - have an expert flash tuner check it out, but if you turn down the boost, and it goes away, then you know it's fuel cut.
