Seems like spent some money on your car so far. Don't you have a wideband gauge or a way to log?

Yeah of course I have a wideband..but my tuner is about 1 hour from me and I don't want to go in my map and mess with the fuel myself...

Anything that alters airmass will alter fuel required. The total amount of change might not be as intense as has been posted however. Alot depends on how close it was to the edge prior. If the car was tuned for 11.0s and now its 11.5s has it changed? Yes of course, as Mike posted though its not going to blow up. If it was 12.0 on meth (too lean for me anyway) and now its 12.5 will it blow up...hard to say but I can guarantee it wont be happy.

Very True Aaron, and I have no doubt that you also have done an exceptional amount of testing on this. Once Baro gets finalized I will have Jason convert mine over to SD as well. BTW thanks for doing the testing and retesting that you have done that has benefited the community. You guys turn out some awesome cars up there.

Actually mike was right the car feels like it need to be tweaked a bit after the 4 inch pipe with the bigger filter..
