I think bigwig gave you some good info in your other thread.

 

EDIT: 12.5 A/F is too lean in boost under any circumstance/setup in my opinion

Fuel Lo looks horrible. Fuel high is OK. Timing seems to be somewhat conservative(depending on fuel being used). Your partial throttle(in Fuel Lo table) may have contributed some extra heat which lead to the outcome. Lot's of variables but, the lack of tuning doesn't help. Good luck w/ the rebuild. . I've got some pistons for you in my sig.

12.5:1 is way too lean on pump gas IMO. I agree about that. Your timing looks conservative. I bet it was too lean/hot.

 

i just worked it over. prior toboost i was getting 38 mpg city annd 47 mpg hiway on the bin prior to boost. i then richened it up a lot my car will be running this weekend so ill start tuning it again

 

I like to tune in the 11's (A/F) for pump gas
