I was driving a 90hp ford ranger while my car was down. Around town didn't bother me, but being on the highway made me want to cry. I still have over 400 miles before adding boost so I try to break in on twisty deserted back roads.

So many good memories driving a Ranger. Broke the headlight turn switch. Got it stuck in sand on a job site. Luckily a dozer was on sight to take us out. Actually Rangers suck and I'm not surprised they were discontinued

Total dogs. I was considering a motor swap if this one ever kicked the bucket, but I think I'd rather have something newer, more comfortable, and easier to drive. It's fine as a cheap beater.

I fiddled with my SPC camber arms, and continued to wonder why vdyno is showing me such low output on my CS turbo tune. Don't know if the program is punking me or if I really am only approaching 310hp when I should be like 330-340 or more, but it makes my heart hurt.

When I was stockblock my car had low compression in #3 and I touched 380whp for like a day, and dropped back down to about 340whp soon after. If your block is as tired as mine was before I built it, it'll be difficult to make those numbers. How many miles do you have, and have you done a leakdown test?
94k, 180-185 compression all across as of March, no leakdown done but no signs of excessive blowby AFAIK.

Drove past 70k miles already, so oil change and tire rotation. Car seems a tiny bit loose or twitchy on the highway. I think it's because one of my tires has a lot more thread than the other three. On WOT passes on the highway, the car seems to want to pull to the left, which is where the newer tire is. I might have to get an alignment to try to sort that out.
Funny you say that, I to took advantage of a similar deal and ordered a full egr kit from adapted performance

Out of fuel I'm guessing? I was thinking the same with my BNR S3 and was disappointed I wasn't in the 330whp range. But, after a quick talk with my tuner it was decided that the 310 range was for the best with 93 octane. He said 330 was definitely attainable, but it does make sense to not completely tax out the stock fuel system so we kept it down a notch. Hopefully starting E85 tune here shortly to remedy the lack of power pump only provides.
Oh yeah, running 93 only is absolutely my restriction (plus shitty BATs because summer and TMIC aren't helping at all), but a group of us have uncovered some funky happenings with vdyno, as well.
@JohnnyTightlips dug up an old MSF thread from one of the CS turbo beta testers (since that's what he and I are both running), in which the guy had posted a vdyno graph and the corresponding datalog. In vdyno version 1.2.7, he was showing 295hp using the platform standard of cf1.01 and smoothing 3. We downloaded the log and threw it into our latest version of vdyno, 1.5.1, using the same settings and with weight/tire size matched to his, and it showed us only 276hp. After fiddling with the correction factor, johnny found that cf1.09 in version 1.5.1 gave us identical output (including torque, but I don't remember what the number was) to cf1.01 in version 1.2.7. Curious. At that setting, my datalog shows me 327hp.
We explained the findings to some of the other guys in chat and it came up that @VoodooJef still has an older version of vdyno on one of his PCs, v1.4.0, so we had him load up my datalog and use the standard cf1.01. His version showed me at 331hp; more in line with cf1.09 in v1.5.1 and, presumably, closer to what we would see if we could had access to v1.2.7 to load up the datalog on cf1.01.
Although we can't say with absolute certainty, it seems as if cf1.01 in the latest version of vdyno is no longer our most accurate setting to use, or it's somehow bugged out, and I'm overall pretty convinced at this point that I am actually making more power than the 305ish hp it initially was telling me.
I ultimately asked my tuner (Will@PD) about it, and if he could estimate based on datalogs where I might be in terms of power. His reply was essentially "vdyno sucks [as we've come to suspect], your BATs suck [lol, yep they do], and stop worrying about numbers and just enjoy driving it." So, that's where I'm at now. I want to eventually hit a real dyno and see what it tells me for comparison, but we'll see if I actually get around to doing that before I've saved up the funds to add WMI to my setup.

@SharksInSpace that's interesting about vdyno @Chemmedic is also around the 320whp mark with it these days running a gtx2971r with Cobb fmic (I think that's what's in there turbo wise can't quite remember) I've told him about this find and we'll see what happens on previous tunes I know he was 20+whp higher so I'm curious to see. At the end of the day your tuner is right though, just enjoy driving it but it's nice in the car community when you've built the block etc to actually be able to back it up, guess you gotta find a real dyno

That is definitely interesting @SharksInSpace . I just looked and I am still on Vdyno 1.2.7. Best I can tell it's fairly accurate from my one dyno day I've done.
VDyno aside, a really good indicator of power is your 60-100 time, assuming you have a straight, flat logging spot. That'll take all the crazy VDyno factors out of the equation.

Nice, how many km on your car?
Roughly 48k
