Downpipe install done! Pretty easy install. Was worried I'd have issues since I didn't order new v clamps, but there just isn't any rust on this car so everything came off and went on smoothly. New coils in and plugs gapped to .020. Car is running great! Can now run Map 2 and logs look super clean. Feel like it could be hitting a little more boost. Trying to figure out FF, wgdc, and PID logic on the JB4. Car has a little fish bite misfire on cold start. Only lasts about 10 seconds. Think I'm gonna try to clean VANOS solenoids and see if that makes it better.
Other than that I'm pretty good for now. On the lookout for a FMIC. Trying to find a good deal on a used one. Debating on whether I should pull my meth injection kit off my other car and install it. But it's an AEM progressive with boost reference. No real failsafe on it except for a relay I wired in the Impala to pull timing in the tune if the controller ever fail-safes. Probably just gonna start by going 30-40% e85.
