well with my mods in sig im running a stage 2 + sf 93 for about 4,000 miles. give or take. well i always use to idle at 14.7 or .8 and now i noticed i cant get over 14.2 at idle and im worried it has changed at cruising and wot. any ideas?

Summer blend of fuel has arrived ?

 

[mazdasp33d]

that was my initial thought... summer temperature and fuel...

What does the DashHawk say at WOT in 3rd gear pull ?

A/F at idle should be stoich. "Summer fuel" has nothing to do with it.

What are the LTFT's?

 

[mazdasp33d]
