I have the beta 4.2 awsome tune but dose not cruise down the road very well. which tune would cruise good down the road but still be close on hp? my trucks rail pressure bounces up and down about 1,500 to 2,000psi just cruising down the road kinda anoying.

 

Both the 4.3 an 4.4 would cruise better, their throttle response is not near as touchy. The 411 Also works well. If you pm me your email, I can send them to you.
