VR Tuned ECU Tuning Box

[Jonathan Lasich]

Jonathan, Thats not bad, but I spent an hour on the phone with someone working directly with Pressertech. I guess just because we dont see them doesnt mean they arent working on the stinger o_o ! @eflyguy may know more, but i am being told there is a stage 3 beta out there being tested! This will also be the same tune that the Big Turbo guys use next for testing.

DaBears, I totally agree. I've been in contact with Todd himself on several occasions in the past and was told that he did some further development of his initial tune on a Stinger with catless secondary pipes on a dyno, so there is some progression. I like to keep things simple and am avoiding a tune that requires some associated mods with it. A nice bump in power from a no "fan fair" tuner who just quietly delivers what he promises!

That's all you can ask for right. It's the quiet guys you should always worry about. His tune might be off the charts in terms of drag racing. The amount of HP and TQ gains matter but how you set the parameters and map everything is what's going to really net you the best times and traps. Very interesting what hes doing. I considered him a one and done based on what I've seen. I was very wrong. He has a big hand in what is going on with our platform and helping take it to GTR levels.

We have a stock pressertech running 4.20 0-60 in the #10 spot of the 0-60 thread.
But for the $350 price diff I'd go tork and get a free intake or 40 six packs.
I dynoed at 407 hp at the wheels with a catback and tork stage1 on a dynojet so they are pretty close.
I'm also not a big fan of PTs crank hp conversion as it is misleading. Crank conversion isn't aweful but also show the stock actual which is prob closer to 390hp. It's the little things....

There mentioned they were going to do an updated for a few months have you seen those numbers yet? I'm sure it's been on a dyno to change data in the tune. Especially with you getting quite a few iterations to your tune. Running 22 psi you should be around 500 hp if not more.

I remember the RaceChip tech mentioning that 20PSI is the top efficiency range of the turbo and 25PSI being the ceiling before she blows. Running 22psi just seems a bit on the risky side to me but for people wanting to push the 1/4 mile envelop might be happy.

Probably for a piggyback. I know tuners that are saying 27 is the ceiling for the stock turbos. Properly tuned cars should have no issues running 22 psi

Jesus, 27 PSI!! That's a hair short of 2 Bar! That's insane! Hope those connecting rods are mighty strong!

Lap3 ecu w wmi at 22 lbs hits 490. Not sure what timing they are running. Their non wmi ecu tune is 440-450. Torks car is 450ish and our tunes are almost the same. Not sure if he holds 22 psi or not with the catless. Pretty sure I'm under 460. When stage 2 is done I'll hit the dyno.
I think I'm fast with a good launch and 1-2 shift.

I'm not sure where you got your "45" HP figure from, but one of our forum members had his AWD tuned by Pressertech. Pre-tune HP on the dyno= 318.
Post-tune= 383
That's 65 wheel HP with K&N drop-in filters as the only other mod. Factor in a 20% driveline loss for the AWD and your 65 wheel HP increase becomes 78 crank HP. To me, that's a reasonable increase for $1200 tune that does not require aftermarket gapped plugs.

The only forum member I'm aware of who has dyno'd a car with Pressertech tune is Mister Mac. His car made 383 whp. Stock Stinger makes 325-330 whp. It's a 53-58 whp gain (I was off by 8 whp) for $1250.

I didn't say it isn't worth the price. I said I don't understand why someone would spend so much ($1200+) for so little (50-60 hp). There are cheaper options available that will do more for the car (Tork, JB4, Racechip ).

That's all anyone could possibly ask for:
Stinger Gran Touring comfort and daily driveability with GT-R level acceleration!

To be fair he's not using a Dragy so we can only assume his time is equal to Dragy's 1-foot rollout times (which has mine under 4 seconds). I don't think his should be on your list.

20psi at low RPM is a lot different than 20psi at high RPM.

PresserTech also mentions that stock plugs are fine like Tork's. I am guessing the piggybacks are the only real concern with plugs.

I'm pretty sure his device doesn't include a 1 foot roll out. The slope argument would be stronger but dragy is terrible on slope especially for 0-60. My drag strip is showing -.17 to -.73% slope on 0-60. Also I ran up a 5% slope and my 0-60 was the same as flat.
There aren't many PT Tunes so its good to have something for people to reference.
He is also at the #10 spot and I expanded the list to 12 and then to 15 so he isn't knocking anyone out. When he gets a little faster we will mail him a dragy.

I have an old GTech pro performance meter I'll try to find and attach to my windshield, then tell you how far off from Dragy it is. My guess is no more accurate than an OBD2 device which are terribly inaccurate. The devices like the Escort only measure g-force and calculate how far the car travels and then calculates the speed based on that, all using the 1G = 32ft/sec/sec base calculation. It's pretty basic and you could do the same in Excel if you had timestamps and g-force ratings.

That will be a good test but how will you measure your actual 0-60 time? Dragy is with in a tenth but you won't know which one is off. I guess you can do several runs and share the averages.
I just looked at several 330 foot track times vs dragy which are in the 5 second range and dragy is off +.06, +.05, -.04.

Dragy is the standard, it will have to be referenced as the actual value. 0.05 second average difference is outstandingly accurate

Dragy is the cheapest useful tool for measuring performance metrics. Anything with a GTECH or any other accelerometer is total garbage in comparison.

this is getting interesting

We will see after Brankys testing.
I'm not saying the gforce is more accurate I'm just saying it isn't that relevent at the #10 spot for 0-60 times.
Plus being the only pressertech time we have, something is better than nothing. Has to be more accurate than obd and it is a purpose built device.
