There are a number of things holding the car back at this point, but the BOV was the most glaring. Hoses were also popping off once the boost was turned up, so some of them may still be leaking. Once those issues are fixed it should perform better, but the car still needs:
3" full exhaust with a good muffler
larger throttle body
better intake manifold
then the exhaust manifold may become an issue
We’ll see what happens. The Haltech is handling the fuel management well. I’m happy with the way it’s held the tune I put on it.
The AEM gauge doesn’t read below 11.0 a/f. He’s at 10.9 in spots at the moment. The car is struggling to get the air out and I’m betting it needs the fuel cooling. Once Bryan gets the EGT gauge in we’ll see about leaning it out, but it didn’t make any more power in that RPM range when it was run leaner.
