Im a running 4.2 beta right now and was wondering what i could stack with it like some kind of pressure box?? I just dont know if its safe to add pressure to 4.2??

 

mp8 , Edge EZ , Dr Performance, etc are all good for adding pressure , but the stock pump may drain rail , & be a limiting factor ?

But lot's of guys love that stack !

I have tried the TNT-R race, 4.3 beta , 4.4 beta
and all are killer tunes.

would like to give the 4.2 beta a try someday !

heard lot's of good things about that tune !

 

Yeap, I have heard great things about the 4.2 on the 03 trucks. I have a copy of it, but I like my TNT so much its just hard to give it a try. Someday I will have too.. I heard it makes good RP so I am not sure about a stack, just be carefull not to add too much pressure.

 

do you think the 4.2 works better than the Revo TNT? I would think that since the 4.2 adds pressure, when you add pressure box, you'd kill stock sticks in no time... you'd def need aft mkt sticks

 

Ya i love the 4.2 its so nasty, i would like to run tnt put my truck dosent like it

 

Mine neither. For me I love 4.3 with some pressure from the MP-8, but my OFE don't seem to like it much anymore. 4.3 is less touchy but just as powerful at wot on my truck compared to 4.2.

 

It doesn't add much if any overall pressure, it just ramps it up quicker.

 

I am running the Beta 4.2 on sw9 and the mp8 at around 30% to 40% for every day driving and It works great for me. I will try TNT when it gets warmer around these parts.

 

Well crap.. I loved the 4.2, but I thought it add to much pressure to stack with MP8.... I'll try it tomorrow...

 

Get on it Let us know how you like it, the 4.2 w/ my X2 pressure only, I still only see 26500 max RP. With the 4.2 only I see 25000 tops.
