These are the mods that I currently have in my 01:
JDM single J39 chip
Cold air
Breather cap
Boost bypass
4# lower pulley
Line mod valve w/ deep sump tranny pan
NGK tr6's
Silver Bullet (on order)

What should I get next? The electric fan w/ water pump or Accufab TB?

Thanks
Later

 

Id say go with the Cobra R waterpump/electric fan. Ive seen people who were like 'wow, I paid 500$ for what?'. The waterpump and e-fan together should give you 15hp or so I believe... Just my .02$

Ya I agree
Go with the fan and waterpump, not only will you free up HP, but your truck will be quieter.

 

Like Don said, E-Fan and W-pump will do more 4 your dough than a T-body, you'll love the fan, John H.
