When I had a chip burned for my car tech said for has some ECU's that mess with the timing and causes the timing to change.<br /><br />My second suggestion is: Is the outer ring on the harmonic balancer slipping? If you haven't checked this. Here is the way to do it.<br />Pull the #1 spark-plug out, insert a wooden dowel and hand crank the engine to top dead center and When the dowel stops moving, make a mark on the balancer. Continue to rotate the crank by hand and when the dowel starts moving down, mark the balancer again. TDC should be in the middle of those two marks, or very close. if it isn't, your ring might be slipping and giving you a false reading.<br />Lastly, did you relocate your air charge temp sensor from the intake manifold to the cold air intake to send the ECU a false reading? I wonder if this is my issue to. This is just a theory...<br />LMK if any of these help, Rick<br />Plan D: do you have a boost retard unit that pulls timing as your boost rises? MAP/BAR sensor bad?<br /> <br /> <small>[ December 29, 2012, 11:36 PM: Message edited by: Ricks Hot Rod Lincoln ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Ricks Hot Rod Lincoln</b> <br /><small>Member # 7637</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2012,11,29,23,45,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Crap, now I thought of another...<br />Did you install a aftermarket oil pump drive that is heavy duty like what ARP sells?
