I've had an issue ever since I fitted the supercharger, I've not been able to get it running right. What happens is:

1) Start from cold, runs fine, warms up fine and idles perfectly once coolant reaches 80c, in closed loop mode.

2) Once warmed up, after an indetermined amount of time, the "issue" begins.

3) The "issue" consists of rough running, with an AFR, according to Torque Pro, of around 16.72, yet my Innovate gauge says 12.0

4) Before the "issue" starts:

my LTFT Bank 1 is -20.31, after the "issue" occurs it is +19.53
my LTFT Bank 2 is -20.31, after the "issue" occurs it is -20.31
my STFT Bank 1 is -11.72, after the "issue" occurs it is +20.31
my STFT Bank 2 is -12.5, after the "issue" occurs it is -11.72

So there is a big change in Bank 1. I have to say thanks to @gavsdav at this point for helping me get to this point, never spotted this before.

I have to reiterate, this never happened before I fitted the Supercharger (TVS1320). I'm using the induction pipe from the groupbuy many years ago (for n/a engines), I'm running I think 45/50 psi (Gouky recommended a guidance pressure which I've copied). Not sure if there is any more relevant information to add?

Thoughts from you clever lot? I'm going to cross-post this onto MR2OC.com as well, I don't want to miss another summer of driving!!
