I was riding my car pritty hard today and all of a sudden i was shifting into forth gear and bam..... No more psi. I hear the turbo wanting to spool up but it seems something is stopping it and i do not know what it is... My check engine light came on and i have no boost build up. It feels like i am driving my SXT again. I have done the following

1 checked all vacum lines
2 tried to reset the computer
3 checked connection on MAS and air box

maybe it just needs to get cold and reset itself

any help would be great I AM NEW TO TURBOS and my car only has 400 miles on it

here is some more info

I did let the car sit for 20 min maybe thinking it went in limp mode..Still same problem

I am pritty sure i do not have a leak

Where you in a mad acceleration when your boost retired ?

That certainly is strange ...

It sounds like you went into limp mode. that can be caused by missfire along with other things. take it to your dealership and have them look at it. and as far as i know you need to have the code cleared by a scanner before it will return to normal.

Don't panic! See my post under this heading for details and a copy of the TSB.

"Turbo shut down at 4500km! READ!" in this forum.

My CSRT4 used to do the same thing. First thing they though was the spark plugs where wrongly gapped. It happened again and they determined to be the fuel injectors. I have not had an issue with it since they replaced them. It has been over 4000 miles since then. Try that

took it to the shop ram cell code message was turbo is not produceing boost. So they ordered a new turbo for the car i should have it in a week

Just wondering if they checked the input and output clamps at the intercooler as there were several posts by crst4 owners covering loss of boost because these were loose.

Just had the exact same thing happen to me in my SRT4.

There is a software update required for the car that is supposed to be done before delivery. It would seem that it does not always get done... or some cars were sold and delivered prior to the update.

i am new to this forum but here goes. I had the same problem with the boost. The dealer went through the same things everyone has mentioned, plugs, wires, injectors. They would replace the items , reset the computer. It would run for a day or two then the check engine would come on. The problem was a faulty computer module. A problem identified is the dodge manual does not list a different part number for an srt4 module, so if the dealer is not careful they will order and install a non-srt4 specified module in the car. Unfortunately these modules are new to market and at the time was not available "off the shelf" and they can not just swap one off another srt4 because the vehicle id is programmed into the module. Total down time was a little over a week while a new module was assembled, shipped and installed. Since then no further issues.
