So I have a tuning issue. mods for car in profile. between i believe 91 and 100 degrees coolant temp my car has rediculous idle surge and huge afr flux (which is a given 
). I tried adjusting fuel enrichment vs temp and pretty much everything pertinent with no improvement. its in sd, their is about 16 inches of vacuum line between sensor and IM, y'd off the fpr line. After those temps, everything is back to groovy. No boost leaks (up to 30psi), Ive checked multiple times, tried multiple ISCs, biss is set correctly. Tune is just for winter 93 oct idle time as it isnt driven in winter (so tune isnt 100% for high boost/pulls but timing is set low anyways), but also occurs with e85 tune. Getting a little frustrated with it and could use some fresh insight. it could be something obvious im overlooking due to aggravation . ill post a log later when i have access to my laptop. thanks in advance.
