VRtune DynoJet Run
As promised
here are last night DynoJet run with and JoeZ intake pipe with K&N dropin
I did 2 runs the first 1st Run in Red color one was done after flashing the VRtune and driving over 1000+ miles for the ECU adaptation period
the 2nd Run in blue color was done with a fresh VRtune flash on the dynoJet with out adaptation and did the ECU reset
ALL runs was done in 4th gear
here some screen picture of the same run
VRTune DynoJet run
Next is a Base Stock run later when i have time

so 194 on my car or even 201 are still gains
lets do a small math
162-194= 32 WHP
its holding up nicely

I'll await your bone stock dyno numbers then. Even VR showed a very unimpressive 7whp gain on a 250 (which is ironically the same gain you show between the two graphs)... If its this inconsistent, even more the reason to avoid this product. Your only proof thus far is that it loses power after time. Like i said, i'll await your bone stock number so we can do the actual math.

Another CL member posted his before and after dyno results from his 2014 GS350 after driving 700 miles with the VR "flash":

From the linked thread above (700 miles driven after "tuning"):
"For the lazy...
BASELINE
Run 1: 247hp/226tq
Run 2: 250hp/227tq
Run 3: 253hp/227tq
"TUNED"
Run 1: 239hp/218tq
Run 2: 245hp/221tq
Run 3: 251hp/227tq
An average loss of 5whp after the tune. "

i am guessing the vr tuned chip is trash?. also wanted to say that i found this other chip called gte performance chip. it seems to be the same as vrtuned just different name and cost less. $99. anyways was planning on getting this but after reading thrue pages on this thread i dont think i will be purchasing this product.

I'm glad you guys wrote this up cause I was interested in getting it. Not anymore. Lol. I'mma wait til others have confirmed this to be true. Sucks we can't do much with this engine, as of yet. I've seen the people getting nos, turbo, supercharger but I don't have that kind of money to do that.

[QUOTE=heyarms;8801980]Novel uses SARD if i understand correctly. Although SARD does offer a tune for the JDM 2IS and ISF, they do not offer a tune for USDM 2IS.
Anymore info on this? What kind of tune do they offer? Is there anyway we a usdm can convert to a JDM one for the tune to work ?

I remember looking into this when this whole VIVID Racing thing came out. Quick answer YES you can easily swap out a USDM ECU for a JDM ECU. The pins and harness is exactly the same. HOWEVER, you have to get passed the immobilizer which I don't think anyone has successfully done; you wont pass USDM emissions with a JDM ECU (thats why the old honda guys used Pre 96 ECU's on those tuned civics); AND you still have to get the software with an authorized tuner to actually DO the work. And last I remember, all of SARD's stuff is in Japanese and I cant read Japanese nor can my local tuner.
There was a thread from Lexus Owners Club AU (Australia) that convinced the owner of SARD to come their country to tune their cars. He charged $4,200 per car, minimum 10 cars plus flight/stay and amenities.
At that point, you are already a couple grand deep (about 1/4 to 1/2 of what the car is worth) for un-promised amount HP gains which is NOT worth it. At that point, its just easier to invest in a faster easier to tune car
