First things first. Untuned. yes I know get a tune so on so forth but I just need it to run right now.
So basically I ran it on a ls ecu on 8 pounds and it ran fine. But I switched to a chipped p28 and it bogs under boost. Once it starts building up the car just bogs out and no matter how much throttle I give it, it doesnt go anywhere rpms get stuck. Im on a fmu and missing link. yes I know bootleg. And once again tunes coming soon.

 

search get tuned... waiting for your next blown motor thread..

 

If it ran fine with another ECU, the tune will most likely fix the problem. My car wouldn't go over 4k RPM before I tuned it due to being super rich. Oh, and stay out of boost until you get it tuned.

 

You've answered all of your questions so whats the point of this thread?

 

 

no gauges and stock ecu chips wtf :S

 

Yea.. you've answered your own question. Get a tune asap.


This just kills me... seriously!? The answer is NOT to give it more throttle if it's falling on its face..lol

 

When it bogs under boost just keep your right foot planted it will sort itself out. The FMU and missing link take a few seconds to kick in.

 

haha, i spit my water out at work lol

To the op:get it tuned, stop driving it, or prepare to be replacing the engine if its not already damaged from you trying to boost on a stock ecu

 

LOL

 

mostly likely the car is going dead rich. the chipped p28 may already have a basemap on it adding fuel, plus the fmu is adding a ton of fuel. remove the fmu and get a decent basemap. then STOP BOOSTING and drive normal until the car is tuned properly.

you came on here knowing the answer to your question but asked it anyways...
