Unless you're running a stage 3 or dual CP3s, I don't think you'll see much difference between level 5 and 7, and definitely not much between 7 and 9. No difference between 7 and 9 in my truck with 90hp injectors and a Stage 2 pump. I even ran the rail low on my last dyno run with level 7.

Are you sure? I thought after you passed though all the options with ">" it changed? Why is it I can change timing like that and notice a rattle and more smoke with out reprogramming? I really need to try the 4.2 so I can compare them

did you change sw levels at the same time that you changed timing settings? if not i'm not sure what you're seeing. but whenever you go into the "adjust options menu, you can change speed limiter, shift limiter, tm, timing, rp, and wastegate (on, off). once these items are changed it is saved to smarty's memory. this means that anytime you change between sw 1-9 then those settings are automatically applied. but you first have to either change between sw 1-9 or reprogram the current sw level that you had applied before you adjusted everything else. i hope this makes sense

let me get your opinion on something. i did a wide open run yesterday with tnt sw9 rp2 tm4 tim3. i still have a stock fuel system and my rail pressure maintained a steady 21,000 psi and my fp didn't drop below 5psi. i know my injectors are holding me back but i still seem to have enough fuel to be running this setting right? i'm asking because i have a fass at home, and i would like to dyno soon but i don't want to go to the hassle of droping my tank and putting the fass on unless i have to.

as long as you're holding rail pressure, you're good to dyno... I'd put the FASS on there when you get a chance though. Let me know when you turn that TM down... made my truck SO much nicer to drive when I backed the TM back to mild!!!!

Unless I am blind (And I might be) I don't see a Turbo upgrade. I see EGT's getting way up there. Also I dyno'd mine on #9 thinking more is better. RP was fine during the Dyno test. But, after playing around with it on the street\#7 feels more powerful and the truck feels quicker, with similar RP, with less EGT's and smoke. I wish I had dyno'd it on #7 also.

Lucky number 7 is my favorite SW.

4.2 does not hold a candle to TNT.

I don't know why everyone thinks that any of the older betas have a chance...keep tuning to you find the "right" settings for your truck.

#7 is also my favorite, a lot less smoke and SOP probably more power.

did you notice any difference in mpg going to a lower tm?

hey guys, question here. 2 weeks ago ran a 12.93 in level 5,t/q at 3,timing at#2 after market inj, RP at #3, W/G off. saw my egts at around 1550 across the line. what adjustments do you guys reccomend for quicker et's and maybe a little cooler egt's. just got the smarty, and im still learning. thanks

I've never calculated mileage because I don't pay for fuel, but I have to imagine it's better as I'm not fogging out intersections trying to pull away gently anymore!
