Whats up first post,
I have a 04 blue srt4 manual boost controller 15 psi, 3 inch downpipe mopar cat back,180 degree thermostat,motormounts,
mopar blowoff valve, ngk iridiums, mopar race wires, k@n cold air intake. what kind of horsepower do you think im running.
also i have never had a problem with boost it always held where ever i set it, but now it spikes to 15 and drops fast to about ten?

 

Too much boost perhaps? Not an expert by far but do remeber reading an article that the blow off valve has to be altered with stiffer springs to allow for higher boost levels otherwise it will do as it is supposed to and expunge excess pressure.

 

that cold weather is kicking in and that always causes changes in boost but thats normal!!!! and your HP who knows go dyno it if no stage kit i dont think much from stock although downpipes are kool.

 

I don't see any stage upgrades so I will assume you are running stock lines. Two things. 1. you have a potential boost leak and 2. cold weather lower's boost but raises timing to compensate.

srtdre, im still trying to understand what you are saying. He has a mopar rice plate, not a bov. Stock surge valve will not have anything to do with boost unless it leaks.
