what converter do you guys think i should get, i was thinking 2500 to 2800, what so bad about the tb spacer?

 

It does not do any good and might be costing you. Drill and tap it for N20

 

Somethings up with your mph...I ran a 15.02@90.6X (2.22 60ft) with hypertech, no cats, custom cold air, and 3.42s open locker in my ex cab 2wd.

 

Cam, weather maybe?

 

the spacer is not hurting you at all i ran 12.59 with mine so you'll can get off the trip of the spacer hurting him,it is not hurting.
i would do a lsd soon and some drag radials then look at your times you will probably need close to a 2800 to 3000 stall for that cam.

 

Maybe you would have gone 12.4X with out it

 

AND MAYBE I WOULD RUN A 13.86

 

do you guys think i should get the tune looked at? whats an lsd? i was thinking on getting the bigger converter, lt's, locker, and some street radials then get it retuned, what do yall think i'll run with this setup?

 

how can the spacer hurt me? what can it do to hurt the time? is it a restriction? or what,
if yall say i would be better with out it i'll remove it but i want to know why is it bad?

 

lsd = limited slip differential locker is not good for the street

yes the spacer is a restriction, it disrupts the smooth airflow.
