problem with boost
problem with boost
Ok, so i have a stage 1+ with the 10.5 hotside
After Shiv custom tuned it, it peaks and holds at 22psi flat. This was, strangely, in both cold and warmer temperatures.
Now, it only peaks at 21psi and sometimes tapers to 20.
Should i be worried? I checked all the vacuum hoses and IC pipes and nothing seems to be leaking.
I cannot hit past 21 psi anymore, even in super cold weather.
what gives?

With my luck, can you blame me?
the first time i had it tuned, the bov was bad and the sparkplugs were bad.
the second time, my coils gave out.

1psi is well within the mechanical variance of any wastegate. Boost pressure will change with temp, humidity, baro, etc,. FWIW, I've also seen mechanical boost guages get severely out-of-calibration over the course of time.
Also, I can assure you that your boost was never flat at 22 all the way to redline. It always tapered down a few psi by fuel cut. Perfectly normal.

Great response Shiv and apropos. However, he has had some real issues,like coils, in the past.
