My VRP/VRUS/Victor Custom Tune with Dyno Sheets.

Long story short my car was not making the power it was supposed to, I contact Victor directly he offer to help me. I borrowed a VRP Self tuning kit from Sunil @ Motorwerks of Houston and headed out to Kurt Deckers Dyno. My car has a Stage 1 VRP Power package, cooling mods and a X pipe. Dyno was a Mustang.
With all the negative stuff going on with VRP on the forums, my experience was the opposite, Victor was very helpful, no doubt it took us some time to coordinate our schedules but it was worth it as you can see from the graphs. AFTER 495 rwhp 560 rwtq

We did about 7 pulls. After each pull we would email the graphs to victor and he would email a new ecu file. I used the self tuning kit to flash it on the car. I know he is now selling these kits to the public so if anyone is interested contact him.

I'm personally a stickler when it comes to AFR's and to me Your air/fuel looks rich. Some may call it "safe" but in all honesty if you lean it out to some place in the 12's You will make more power and still be "safe."

With that said, you still got some more tuning to do. Thats a good thing though because you will make more power.

You will pick up some power once you lean it out a bit. Keep at it, you're just about there

Isn't 12.6 a pretty optimal number for A/F ratio.... you are right it's way rich.

Nicely done and glad you got through to VRUS.

What tune are you running now? Are you the only VRP tune vs a PC based one?

Do you know retail for the "self" tune tool? I assume it is a flash booster, which i have been dying to get!!

+1 to both of these. Congrats shardul, those are good-lookin' results and should only get better with some tweaking.

12.6 is a little on the lean side for a forced induction car. At least for something I would drive everyday.

good numbers. Looks like the previous VRP tune was too safe and had plenty more to squeeze out.

I wouldn't tune to 12.5 afr. I'd like to keep it under 12.0 at redline. Although you are still running very rich

Glad you are making the power that you should be seeing with the mods you got.

We should be able to knock out the exhaust modifications when your down this weekend. Either at my shop or at my buddies.

It may be running a little rich, but in warm weather that extra fuel will help keep cylinder temps down, better safe than sorry.

I would recommend high 11's, not high 10s

Great #'s Shardul, thanks for sharing. I have to say, I really like that you included the graph along with some pictures for the rest of us.

These "self tune kits", are there any files open to to the end user? Or does any change require uploading to VRUS?

The self tune kit is an interface used to load the file on the car. You cannot modify the file only victor can do that.
The reason these tune kits are becoming popular is because you don't have to ship the ecu out and you can custom tune the car remotely.
