I got a nice clean data log of a 2nd gear full throttle pull. Here's my new boost curve:




And here it is compared to my boost curve with the exhaust leak:




Lesson: Make sure your exhaust system is leak free when you have a turbo, or else you'll be missing out on power and turbo response!


And for a fun comparison, I found this dyno chart of a RIPP supercharged 3.6 Wrangler, with a boost curve. Notice that the boost curve is not actually linear. It seems to be a shallow exponential curve. If it was linear, it would have 5 psi around 3250 rpm (half peak boost at half peak engine speed), but it doesn't actually reach 5 psi until 4600 rpm!
