Let me start off by saying vishnu products are the bomb, and I have never had any problems with them.

I have had the engine knock or lock- up or somthing to that effect twice now. One was a third gear pull the other was a fourth. During hard acceleration the engine felt like it just locked up. Both times it was cold out but the car was warmed up. My car also feels like it is cutting out a little. I have zero + Any ideas on what is the cause.

Note it has been around 10-degrees with a sub 0 wind factor. I have been out in the cold before and it not do that before. I know these cars are finiky, but the knock was pretty hard.

 

boost cut?

Sounds like boost cut to me.

 

I have the 0+ also. Mine has been doing the same thing occasionally now that its cold out.

 

You need to go into your XEDE and lower the values in the boost table. Press "<" three times on the highlighted cells and it will lower boost about 1 psi.

 

you could have been a dolphin and I would have understood more.J/K

Thanks for the assistance, I will give it a try. It was <10-degrees for 5 days and now it was like 50-degrees outside and it is running very strong. why does the boost cut in the colder weather.

And you said 3 should do it.

 

because colder air is more dense

 

that's funny
