4th gear lock out?
 

Anyone having issues with this? 1-2-3 is fine on no-lift, but when i try to shift to 4th it locks me out of going into gear. sometimes it's fine but most of the time it lock out. i've also tried to shift early to see if i was to high of RPM, i shift at 6K.

Also, i did the rod adjustment, and some say that they boost to 20lbs. mine only boost to 17-18 if lucky. Did the computer learn the boost levels and is it holding it back? Or would it be because i have no other mods done to the car?

Thanks for any info, Geoff
