were pretty much in line as before. this time the dyno showed 3hp less and 5 tq less then before w/ spacer. it could have been the heaters in the bay area due to being so cold outside but i know each time it could be different results +/- 5hp/tq.....Also, the garage doors were half way opened when it was time to run on the machine as a note.The main reason i went back to my tuner was because of the added piece to hold my jlt filter in place. JLT said it would most likely run lean with this piece in place. he was right! above 6000 rpm the air/fuel went from about 12 to about 10. JDM also update the tune with better pull from start to finish. to me it feels alot better and faster. ill just have to wait and see what kind of difference when the track opens again.

 

thanks for posting it, I'll do the same for my setup too when I redyno.

Are you sure you didn't misunderstand what JLT said? Going from a/f of 12 to 10 is going very rich, not lean.
