it shouldnt be at 14 something stock, if so its hurting for power. Stoich is at 14.7 and when you're cruising on the highway it'll be at that but at WOT it should be atleast 13.5. On spray I think most aim for around 12.1, NA about 12.8-13.0.<b>Black</b> 1998 Pontiac <i>Firebird</i> A-4 swap<br />271.4rwhp/259.4rwtq NA<br />13.30@102.44 <br /><a href=\"http://www.freewebs.com/wickedsix98\" target=\"_blank\">www.freewebs.com/wickedsix98</a> -

Lower the number the more rich.
You want to adjust the WOT AFR in the PE Enrichment Add vs RPM table. However, you will want to do this with a WBO2 sensor. Do not try this without a WBO2. Without a WBO2, you have no idea what your AFR is (except above or bellow 14.7) and this will not help you adjust the AFR.2001 Firebird 3.8L V6 M5,<br />It once had....<br />NX Nitrous Wet Kit, ZZP X-P Hot Cam, <br />3.42 LSD, Pacesetter Headers, <br />36# Injectors, HP Tuners<br />322 RWHP, 379 RWTQ<br />13.596 @ 102.56 w/100 shotComment

Yep, leave the stoich setting alone. Do the a/f tuning in PE. (or IFR, or MAF, or VE) Different theories on all that...
But, for nitrous tuning, that's a different story altogether. Is it a wet or a dry shot? Wet tuning is through jet selection. Dry tuning is generally managed through the inherent cooling seen at the maf and the fpr boost from the bypass valve. You can further tweak the wot tune in the pcm for nitrous, but then it will off for for na wot use. Unless you have 2 tunes and switch back and forth.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment

i figured..i dont know that its true but i've heard factories actually make the cars run slightly on the lean side due to emissions regulations...it would be nice but i think this is just more than i want to get involved with..im not really concerned about n/a because i dont race n/a ..it is a dry shot for now..so as John D. was saying..my MAF will pick it up since i have the nozzle in the air box now..for a 75 - 100 shot i'll leave the bypass jet as is..but i may decide to play with it for the 125 shot..thanks a lot for your input guys [img]smile.gif[/img]<b>12 SECOND DUAL STAGE DRY NITROUS POWERED 98 A4 V6 CAMARO<br /><a href=\"http://www.mysickcamaro.50megs.com\" target=\"_blank\">www.MySickCamaro.50megs.com</a><br />Best ET: 12.82@103<br />Best MPH: 104.7<br />Best 60\': 1.75 - Stock TC</b><br /> </font><blockquote><font size=\"1\" face=\"Verdana, Helvetica, sans-serif\">quote:</font><hr /><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">Originally posted by Shodown:<br /><strong>1DV6 runs 12\'s...enough said. </strong></font><hr /></blockquote><font size=\"2\" face=\"Verdana, Helvetica, sans-serif\">Comment
