Engine/Transmission (1998.5 - 2002) What do you recommend for a good smarty stack?

[CRiggan]

Thanks,



A friend's truck of mine is a 99 model. He has an Edge Comp box, Smarty, 275 HP injectors, silver 62, fass 150, and HO vp44.



Is the edge comp and smarty a good stack ? What other stack would be good to stack with Smarty?



Thanks

yes its a very good stack! It dosent use the smarty timing to its advantage, it still times on the edge (Make sure you only use the Non Timing even SW's) ! A tst seems to make a great stack but if you have a edge and stay there unless your shooting for a ton of power! The high timing eventually cause problems! The timing causes higher Cyl. Temps! And Higher Heat soak...
All in one simple line... . Its a great stack for a daily driver with good air and fuel supply!

I thought advanced timing lowered EGT's and raised cylinder pressures?

Thanks for the input. I do not see alot of power increase when my friend dials up the comp above level 2 or more when the smarty is on level 5. The truck runs great and has tons of power

John, i thought raised pressure increased heat soak which raised cylinder temps... . theres so many discussions on it, im not sure which way is up, I can tell a diffrence on my cool down times , it seems like it takes alot longer to cool down with timing, i know advanced timing seems to raise the heat soak..... i think a motor seems to be more affected in a bad way from advanced timing!

Smarty Level 5 adds timing..... levels 2,4,6,8 do not add timing. He should not run the smarty on timing with the edge. He is gonna have engine failure with added timing.

what about the smarty and the van aken box stack?

Smarty and TST work pretty good on my truck.

I have run timing with both and have not noticed any issues. My cool down time does slow down a hair but not to horrible. But granted I dont run it too long or very often, but only because I don't need the extra timing of both usually. However when I am shooting for prolonged HP I run both with it.

the #9 tune on smarty is a timing tune also
