That's about it. Would also add proper throttle control rowing through the gears results in no smoke. It's on tap if you want it though..

 

I haven't slipped mine on 100hp but I haven't been ripping through the gears and burning rubber. Never even tried to spin my tires before and probably never will. It should be fine. I do wonder though about long term effects on the stock clutch even being conservative as I am. When you're in first and you ease out of the clucth you can really feel that extra power want to push the truck forward just at idle with no throttle. It's like a beast that just wants to go. Probably causing more clutch wear but still should last a while. I'm saving for a South Bend just in case. Can anyone suggest which one with this Jr being my last power upgrade?

 

2 weeks with the new Smarty Jr.. 40 Hp setting is okay. Way better throttle response. More pep to the step but not all that exciting. I don't think I will run that setting again. Didn't notice any smoke. Went from the 40 Hp setting to the 100 Hp setting. What a difference. From a slow rolling start there is just a really quick lag and then it jumps to life. I have 315's on my truck and it lights them up when you jump on it. A nice big puff of smoke when the power hits but that's about it. Only from a dead stop or very slow rolling start. I layed into it all the way up to 80 mph and it just kept pulling. The intake and exhaust were breathing full on and it had me stuck in the seat with a big smile. Normal driving and accelerating I haven't noticed any smoke at all. It def. rattles and runs differently at idle or slow speed. Nothing bad. Just sounds like an older diesel. I ran the 100 Hp setting all week. I drive for work all day. Tow and haul numerous different things throughout the day and I had no problem with EGT's or driveability. If you are just cruising around you really almost don't notice the difference. The pedal isn't as heavy and you can really feel the torque increase on long uphills. I switched it over two days ago to the 70 Hp setting. Less smoke on hard acceleration from a rolling start and the tires hook up the whole time.You will still noticed the smoke but it's just not as thick and as big a cloud. It seems like the smoke hangs on a little longer through the acceleration though. Still not bad at all. At idle it's much smoother. Not as much rattle. I think I like this setting the best so far for everyday driving.

Fuel mileage seems to be about 1.5 to 2 mpg better. I drive around town mostly so there is a lot of start and stop and speed changes. I've been a little heavy on the pedal and have still noticed that gain. I haven't run it enough to really be able to say but it is an improvement and I'm happy so far.

I love it when you buy a product and it works just like it is advertised. It's easy to use and the performance is awesome.

Used the function to adjust for my tires without a problem. Checked for codes and nothing so far.

 

I wonder why they haven’t come out with different tunes for the auto and manual transmissions? The auto guys say they don’t see much smoke, but as a manual guy I’ll attest that I now have “smoke on demand.” I haven’t has any tailgaters lately, but now I’m prepared.

I switched up to the 100 HP setting from the 40 HP setting and would say that possibly the 40 HP setting has more bottom end, however it is hard to tell. I’m thinking I have less smoke with the 100 setting, but maybe I’m just relearning how to shift with the Smarty.

Does the Smarty change the output of the Alternator? Maybe I’m crazy, but it seems like I have more voltage on the gauge, but maybe that thing is fake like the oil pressure gauge, lol?

 

Burned through my first tank on sw5 (100hp) average with quad xzt (60hp) was 18.4 hand calc every fillup over the last six months. This tank on sw5 came out at 18.3 so no gain or really loss either for that matter probably gonna hold steady on fuel consumption with that sw. That was with some heavy foot driving. Maybe the other settings do better but I prefer the power of sw5 and that's where I'm staying. As long as it stays this way over the next few months to have those 100 extra horses on tap and hold steady with the mpgs is pretty good if you ask me.

 

Thats it I cant take it anymore, Im buying one

 

you cant stack a predator with a jr. I was not ragging on my junk when the clutch slipped, i just rolled into the throttle and it let loose.. Probelm is solved now though

 

Im looking at the jr. for my 03 Ca. model standard output (235 H.P.), NV4500 trans. From what I understand Smarty brings this truck up to H.O. output plus the 40, 70, or 100 h.p. That sounds like alot. Even on the 40 H.P setting that will add 140 H.P. Is this correct? Can my truck handle it? I want some towing power, but dont want to tear it up.

 

I have the same CA engine running Smarty... what you understand is correct. the 40 hp setting will net you closer to 100-110hp overall, this is what I have witnessed. Your truck will be ok with the 100hp setting too if your clutch is in good shape and you don't try silly things like 2500rpm 4x4 clutch dump. With everything else on your truck stock, 100hp smarty jr setting should net your CA 235hp engine somewhere in the mid 300's range (RWHP) on the dyno. Get a boost elbow (better to make it yourself) and this will help a little more too...

 

Soulezoo, thanks for the info. With the boost elbow, do I also need a boost fooler so The truck does not throw codes? I read about all these different things but don't know much about them. A lot of info.

 

You will not need the boost fooler--- smarty jr already does it. Besides, you are only talking about going from 23psi max to maybe 30psi if lucky. But the extra 5-7 lbs of boost is a good thing.

 

Anyone hook up and tow 10K with the JR yet? I am curious how the EGT's were with a heavy load... and which setting was best. If the 40hp is timing only is it too much for heavy loads (mads eluded it may be in an email)... And how does the clutch like 70hp and 10K in tow?

 

I towed that much with the 100 hp file... egts were about 1000-1100 max, but I have twins too....

 

The do not tow on the lowest setting is for the 2nd gen vp44 trucks only. This warning does not apply to the CR CP3 3rd gen trucks.

 

Right, but I have an email from mads saying that you may get timing rattle if you tow a heavy load on the 40hp setting.. just wondering if anyone has experienced it.
