Alright so i've recently been wanting to get a tune from Nelson for my 1997 RCLB and I was hoping you guys, or Allen could chime in on some questions I have. The truck currently has a 4.3 (I know, weaksauce) and stock trans, it will eventually have an lq4 and other goodies but not till I graduate next year. So, if I get a tune now, would it help at all with the ity bitty 4.3? Also, if I get one now, it's my understanding when I get the new PCM for the lq4 I'll have to pay for the new tune, right? I was thinking it'd be a good investment for the time being until I get my new setup, what do yall think?
