So I have some concerns about my t2 now that I'm pretty much done installing all the stuff I'm been waiting for. Car runs, drives, and boost fine for the 5 minute drive but I'm sure things aren't properly tuned so I stopped and decided to ask questions.

4x 720cc (195500-0830)
S5 T2 Rtek 1.8
Aftermarket FPR set to 40psi w/o vacuum
Walbro 255

At idle now it sits at like 500 firm instead of 750ish before the installation, so I'm a little hesitant about it dying if I were to come to a stop from boost, and just for being too low. At idle too my AFR reads 17, which used to be 14.5.
While boosting AFR sits at 13, which also used to be 12-12.5 before.

How can I personally tune it so I can get 13.5-14.5 at idle and 11-12 WOT/boost? I understand that it's harder to tune a piggyback but I'd rather get it tuned with what I have than go standalone. Was debating on a safc but if I can get it there without it than I'll do it.
Also, is the FPR set low? I know stock is 39.8 but I was thinking of bringing it up to about 45psi but want to ask before setting it incase it is too high.

 

increasing the fuel pressure won't hurt anything. You're lean everywhere, so it's worth a shot.

 

How high is too high?

 

go to 50 psi and see if that's too much.

 

Nah.
