well i just got back from xotic motorsports and i'm a bit pleased, but also a bit upset..

i hit 369rwhp and 379rwtq. the curves are perfect and the a/f is dead on. i'm going to post the graph later. the shops' printer was down so they have to email the graphs to me. i paid 50$ and got 6 pulls and with the afc-2 i was able to gain 50rwhp!!!

i know my setup has way more in it. i didnt go past 19psi cause i didn't have race gas and was on 93 octane. i'm going back next week and i'm going to blow this turbo up.

also the washers worked really good and the boost held good all the way till 6300 rpms :)

here is the kicker i made this much power through a cat and a crush-bent exhaust with a 2.5inch muffler on the rear.

stay tune for more number and i will post the graph as soon as i get it.

one question. on the way home i was hitting fuel-cut pretty bad at 19psi, but i wasn't hitting it on the dyno. also the LEX screw has never been touched (all the way in) should i back it out??

also if i back it out, will this affect my a/f ratios. righ tnow there dead on.

Yes, it would affect your A/F ratios. The reason for this it is allowing more unmetered air in causing you to lean out more.

Just curious how NOT moving a screw allows it to change the way an airstream is affected?

You might find that engine load is another factor to consider.

If you are hitting FC @ 19psi you might have a small boost leak. Nice #'s though. :)

yeah man, I wouldnt touch that screw unless I richened the safc2 back up.

On a side note, you can pick up a wideband o2 for almost the cost of a dyno session - so you could just tune it on the street.

You hit fuel cut because you or the tuner didn't compensate for "real world" conditions. When you get a car tuned correctly on the dyno, it's always smart to richen it up just a tiny bit to compensate for real load on the street. The car will run leaner on the street so when most tuners (the good ones) will tune your car, they will richen it up just a tad after they get the curve right.

i would like to see how much your power would jump at open downpipe. why would you try and max out a turbo with a cat and 2.5inch exhaust???

That shouldnt affect FC like that. If the tuner didnt richen it up after the tune on the dyno than the FC would be HIGHER than if he did richened it up. To richen the mixture he would be scaling hte KV signal up more, bringing in FC sonner. I still think its a boost leak. :) Thoughts, opinions?
