hi guys.just wondering what some of you guys are running for main jets on your rx1 with these newer 4 tube headers.i just installed a new 4 tube header from powderlites on my rx1 front mount with a garrett 2860 turbo and the only changes i did was the header and i took it for a ride yesteday and i was very lean on wot.i have 152.5 jets in it now .cant believe how lean it was .it was in the low 13 on my af gauge.these headers do make a difference.what jetting should i put in .i was thinking 160 main jet.what do you figure.thanks for any help.

I'm running my own homebuilt version of that header and with a 2560 I'm still leaner than I like with 150 mains so I plan on going to 155's. I was running at 11.6-11.9 wot before my a/f sensor took a dump.I want to stay in the low 11's hoping the extra fuel will keep my header from cracking. I'm tired of tearing it apart to fix the header.
