How Much Boost?

How much boost does your OBS make. With the mods in my sig I hit 21 psi just punching it on the street from 40 to 60 mph. I expected around 15 max out of the OBS.

Before I opened my exhaust to a 4" strait pipe with a 3" DP, I could hit that with the chip on high.

Now, I only see 15 psi while towing.

When I get new injectors that will be a different story.

So why am I hitting it with a wide open exhaust? 3'' dp, 4'' section(short), 5'' all the way from under cab to stacks.

Pull the chip off and you will see those numbers.

JFines you should only get moreboost with your exhaust done, since it relieves backpressure letting the turbo spool quicker and higher.
