Made a trip to Cali to swap my JB4 for VF Hex tune

[yellowssm]

Ok did a quick up and down the street. The torque is insane! It pulls so much harder than before. Ive never chirped second gear before but just now it chirped second and third and car is a DCT. When throttle is in Sport plus it seems a little more sensitive. The best way to describe it is like turning on the sport button on a e46 m3. Vid coming soon. Will post more impression after the drive home

Drive safe back to Vegas but hammer it as often as possible....you know, for testing purposes.

Did you make it home safely or did the VF flash make so much extra power that you totaled the car already!?😂😂 J/K...

Or ran out of gas and stuck in the dessert

[Yessir]

This looks promising. Stock car on stage 1 made 472hp/510tq, per the other thread .Op car has stage 2 with dps and made 489hp/527tq. So 10- 20 hp/tq more just like the ad claims from stage 1 to stage 2. I like that!!! Real numbers that back up their claims.

Haha made it home safely. The drive home was smooth as butter. No hickups other than that crazy California traffic/construction where 4 lanes go to 2 . The power of this car is crazy, I still cant believe the difference from before. If any of you guys are Las Vegas locals pm me and id happily take you for a ride. The car scares me all over again like the first time I turned traction control fully off and the rear end did its little dance

I kind of thought at first the burbles would get annoying but its so addictive. Personally Ive never heard a car that does this. You also get the best of both worlds with the burbles since you can just throw it in efficient then its perfectly quiet like it was before the VF Hex tune.

The higher HP/Torque gauges are a nice touch along with the GTS start up.

I still have to do more driving around but this was the best investment I have made so far for this car. I will be making another trip down to VF and Supreme Power to get the 2+ and TCU upgrade along with the cable to flash between stages and stock.

I will work on making some videos hopefully this weekend

Stock tune vs JB4 map 1 (all runs have VRSF downpipes, 91 octane, and BMS intake)



JB4 Map 1 vs VF Hex Tuning stage 2 (all runs have VRSF downpipes, 91 octane, and BMS intake)



Stock Tune vs VF Hex tune stage 2 (all runs have VRSF downpipes, 91 octane, and BMS intake)

It was a pleasure meeting you Rey!

[JoeyBananas]

So this tune makes more power on 91 than the Jb4 on Race gas??? Am I understanding N that correctly

You guys were awesome! Let me know when you guys get some swift springs in and ill be back for them along with stage 2+ and the cable.

all test were done on 91. We didn't test race gas.

Quick video of the overrun exhaust burble. Car has downpipes. Sorry for the quality my iphone camera wont focus.

How do you think Stage 1 will work and sound with Akra Slip-On?

I know, that's my point. It looks like you made the same power on 91 that JB4 normally makes on 93 stage2?

Well if that's true that's good to know. Never dyno'd my car on race gas but Ive driven my car on JB4 map 2 on 91oct w/E85 (4.5 gallons) and it feels faster now just on 91 with the Hex stage 2

I wish we had empirical data on that^^, other than seat of the pants feel...

Well you have the stage 2 tune tuning 520wtq on 91 octane...throw in 93 and you're going to get even more.

The fact that this is a flash makes the difference too because there's no delay in values changing like on a piggyback so the resulting power is more instant. I would guess that a flash tune making this kind of power is going to feel and ultimately be faster than a piggy with comparable power

I can see the more responsive/immediate power as making it "feel" faster for sure. But dyno numbers are dyno numbers. The JB4 map 2 w/ 93oct has done in the 490's on different cars if I'm not mistaken with more than that in trq. I guess the VF tune doing it on 91oct is most impressive to me but I'd be VERY curious to know what the VF Stage 2 tune coulda/woulda done had their just been a gallon or two of 100oct race fuel put in to mimick 93+Oct in the tank to see if and HOW MUCH the numbers would really change* This would of been really important for everyone else outside of Cali!

No kidding. Personally I'm not interested in anything dynoed in 91 and a butt dyno

The piggyback tunes alter the sensor values faster than the DME can read them. The reason people sometimes think flash maps feel more responsive is the same reason people buy the sprint-booster device. They run a none linear gas pedal curve so you get full power at half throttle.

It looks to have another few hundred RPM of lag compared to stock? Since this is an analysis thread post up the datalogs from the runs so we can see just how safely this remap is setup. 480whp on a tune, pump gas, and mods, seems pretty common. I've seen lots of 500whp dynos posted so maybe its a bit low?

Well unfortunately 91 is all us west coasters get.
