Hey guys. Well i was currently tuned on 20psi. i just replaced the stock fmic and put an ets 3.5" ic. I also got rid of my hks intake and got the ets intake. My problem is after i installed these mods i am seeing 10.1 afrs not even WOT. If i do like 3/4s throttle these shoot down to 10.2 and lower. Other than that i have not got on it. I think i may have a leak.


But i noticed that my hks intake pipe had 2 nipples on it, one for the line that goes to top of valve cover and one that was hidden at bottom of intake. The new ets intake pipe only came with 1 nipple that was rather large. That one i connected to the line that goes to valve cover. So i have 1 line that is just dangling. Could that be my problem. Why would they make an intake with only 1 nipple unlike the hks one that had 2.

 

should have leaned out with those mods...make sure u dont have a boost leak
