So I have been at like 526hp for like almost 8 months now, and let me tell ya – that settings is not very drivable, and seems to be very hard on the street to control the smoke, etc by the throttle.
And at that power level on the dyno is was no problem to see like 1500-1700* (depends on load and how long you stayed in it) and it was about 46 lbs of boost. (that’s holding the wastgate full open from 40lbs)
SO… quick 4 hour drive to Floor-it Diesel to get some Don M (F1 Diesel) Flux injectors installed and we were going to see exactly how much more we can squeak out of originally a 196hp motor (at the wheels)
First off, Let me tell ya, Scott and John can flat out move when it comes to installing an injector. They made it look easy! I think they could do it sleeping, honestly. (one funny thing is that we turned over the engine with no injectors in to blow out debris, etc – that’s a heck of a site!)
So with injectors in and engine buttoned back up, it took a good 10 seconds to start, and when it did, a nice size cloud was the result. Nice… wrong color though, from all the oil that got into the cylinder, etc
Scott and john took her for a quick drive to check everything out (and to play around, haha) and all seemed well, so onto the dyno she went.
To this day the motor could never get over 526 hp –
TST 8x8 – EZ2 = 526
TST 9x9 – EZ1 = 524
TST 8x8 – EZ1 = 522
(higher EZ levels always made same or less HP, and some times had to turn down the TST)
All the runs were on Johns dyno at various times in the last year and half. , BTW
So now we start with TST on 6x5, EZ2 - That’s nets us a great number of 580. 1. So we try TST 8x8 – that’s nets us like 458hp and WHOLE bunch of smoke. (48lbs of boost though) – TST 7x7 does OK, but only makes 510ish hp
So now we are like, well I guess the first setting was the best – So now we try TST 6x5, EZ3, and there we go, 601hp !!! I could not believe it, the truck only made 42lbs, and was at like 1320* egt.
This does not make any sense. So what do we do? EZ level 4 of course!!! Dyno…. Nope, no good lost 50hp – man is this common rail stuff confusing. Try 5x5, EZ4 – made I think 560ish…
Ok, Although we wanted more. 600 is not too shabby, heck thats's a max gain of 80hp over my best number from all the combos I have ran.
Time for some backup numbers. – next we posted a 602, the another 604. 8hp – nice!!! - -And still about 42lbs and 1300* egt.
And the truck sounds way more wicked, IMO
So the dyno is done, we are happy, 604 on #2 only seems like a nice victory – But heck with dyno sheets, WHATS SHE DRIVE LIKE?!?!?!
One word = SMOOTH – I mean the old 526 setting (tst 8x8,EZ2) was violent and hard to daily drive. It was quite “peaky” as well, not very linear
Now this truck can be driven on 6x5 and when you want it, its there, if not that’s ok. When you floor it, it does not stop pulling till redline – peroid! The smoke is very ample when I want it to be. But that’s nothing new to the TST twins flash. But when I drive “normal” the smoke is not noticeable at all. Heck even on txt 2x2, this truck feels like 450hp EASY – we did not think to dyno without chips on. I will do that this Saturday in St. James though.
Its like a new truck, that’s for sure. I was always a little scared to run it on high, now I love it! The truck almost begs to be ran hard, and at only 42lbs boost, my turbo is loving life. And at 1358 egt on the highway at 100mph end of a big run, I could not be happier. When it was on the old 526hp settings, 1600+ was so easy it was not funny.
SPOOL UP – seems faster, but then again I run less boost now – The best way I can describe it is I feel like I have nitrous now — the turbo seems to come on at the same RPM- BUT yet it feels way faster from from a stop…
BOOST + EGT – already addressed
FUEL MPG – that’s hard to tell, I cant help but run it hard now – it just begs me too! I will report after one tank.
DRIVABLITY – like I said earlier – its like night and day, there’s no way I would go back.
SMOKE – very easy to control, on 6x5, I can make a nice cloud, but totally cleans up by 2200 rpms – 8x8 (though less HP) can shut down a highway easy
IDLE – truck is quieter at idle for some reason, and idle is smoother
That’s about all I can think of now --- one things for sure, Unless someone comes up with something crazy awesome – DON’s injectors will be the only ones found in my truck from now on, period. In fact I cant wait till more levels come out, This MOD was so easy – I mean I have great results, and what did I have to sacrifice? Smoke-no, drivability-no… exactly, I sacrificed nothing!
BTW – DYNO VIDS and DYNO graph will be posted as soon as KevinO emails then to me, (chop-chop Kevin!)
