Default '14 Lexus is250 dyno Run with mods

Hi clubmembers
decided to mod my 2014 lexus is250 bone stock and after getting and instaling a JoeZ intake pipe, K&N filter and VRTune

i went to my dynojet shop to see what are the gains

we I did 2 runs and here are the video:

ALL runs was done in 4th gear




DynoJet run

the results are :
Max power 201 whp
Max torque 180


compare that the to the average stock is250 are around 160-165 whp
the gains are around 40-35 WHP

I DON'T know but that a lot for power Gains from just a tune and intake combo!!

so ill be doing a base stock vs modded dynojet run again at the same day and compare before and after just to get a real feel to compare

we'll keep you updated soon...

Interesting....
So the 184 torque claimed in the stock 250 is actually not true?
Do you think it's worth $700 for this?

well ill be honest with you, to me it worth it bc Stock Vs Tuned its night and day to me, more responsive,more torque in the low to mid range of the RPM for my daily driving habits.

exactly like what Glock47 explained, thanks Glock47

201 WHP and 180 WTQ figures are on the wheel not the 204 crack power and 186 crack torque like whats advertised
well usually power loss in average are 15%-20% which happen between crack going throw the mechanical parts like transmission,drive shaft and into rear differentials and lastly to the wheel
for example if u add 15%-20% power loss to the car 201 WHP and 180 WTQ its making around 231-241 HP and 207-216 WTQ after the conversion

So ultimately it improves your car's HP and torque overall, just that the VRTune Flash provides more efficiency improvements on the wheel?

And.. do you know if it will work on the 2015 model?
I emailed them, but they haven't responded back.

in my case it did make gains and i noticed the torque gains while driving so yeay it did provides more efficiency improvements on the wheel

i think 15' are the same as 14' but you should get a replay from them first

Just got a response from Dan, and he said it's the same for the 2015 model.
Is anyone else interested in this? :P
I found some old threads about VRTuned... and it makes me hesitate:

You should be hesitant. There is no proven tune that exists for these cars. This particular tune has been dyno tested before and after by members of this forum and found no improvement. Also, if you look at what some other car forums think of this tuner you will see that they are a scam.

Yeah, I would only trust stuff like AEM EMS and etc I used to be a Honda guy and used chipped ecu's in the past. Maybe OP got lucky haha

yeah, that's what I think they are...
I actually had a respond from Dan (Owner I assume), after telling him how there is no trust from CL members, and he said "It is proven to work and we have reviews on our site. Unfortunately we cant push forum members to respond.

I thought it's a funny comment....
If it works, and proven, why won't the forum members respond to such thing?

totally agree, if a forum member bought this and it worked, they would tell everyone, because we would probably all buy one...

OP, since you're the only one that has actually done the ECU Tuning with VRTuned, please keep us posted on whether it actually keeps working and doesn't get "de-tuned" after a longer period of time.

He's not the first. Check out this thread. It's an ISF but Vivid claims it works on ISF, 350 and 250. Most importantly, this one has a baseline.
