I dont know what could cause this ? Do I need a different after market DV? Has anyone else had a surging boost issue like this after the revo stg 1?
Most likely a leak if that's the case. Start with a pressure test.its been doing it ever since I got chipped. So what could it be that it wouldnt have been before it was chipped?
x2Surging is typically related to a bad N75 or some sort of leak. Start with a boost leak test (AKA, pressure test), followed by swapping in a known working N75, and finally examining for exhaust leaks (hint: Seafoam).
EDIT: And no, your DV is most likely not the issue unless it's leaking.
The software was created around the stock, N75F valve. Anything else is hit and miss.there are a bunch to choose from on the ECSTuning website. Which one is best for the stg 1 revo set up?
