Disappointed with +40 whp? What were you expecting? :) My car was a little over +40 whp too, prior to going turbo: http://www.ft86club.com/forums/showthread.php?t=53946

Car goes on dyno without tune. No weird dip.

Car goes on dyno with tune. Weird dip.

People go insane defending Vish.

Op doesn't log dyno runs so we can't see what happened.

Vish blames dyno. (it worked fine on the stock tune???)

This is no witch hunt, there is just some missing information. People get so butthurt.

My vote is on traction control as well. Pedal dance when you dyno people!

Smokes! 207whp?!?! The highest I got on the MaHa was 172whp. I'd be happy if I was in your range. :(

Just test on a Dynojet and you will likely be right around there. The Maha dyno reads obnoxiously low for some reason. It doesn't necessarily mean that your car is down on power.

207 whp... haha. Maha reads differently though. I bet you'd be pretty close on a dynojet. :thumbup:

For dynos find one that gives consistent figures, eg. same car 1 month apart gives more-or-less identical graphs, and do all power runs at the same place. That way it's all relative to the same set of systematic errors.

Corrected, sorry!



And you're basically saying, go FI.... :lol:

Like I noted. It wasn't you per se that was the problem here. It was the dyno operator that probably misinformed you likely due to his own bias and/or ability to see his own errors.

I'm going to remind you of your own words here because they don't describe the attitude in the above reply. If you have "no intention of degrading their reputation". Then why would you post your conclusion as fact in your original post? Additionally, why would you end your original post with a call to Shiv to resolve the problem if you weren't placing blame at his feet? Lastly, can you describe in your own words and experience why you personally believe that your Maha dyno session revealed something that all the time Shiv's R&D on his and other dynos has not?


here's your original text

The specialist said he encountered this also on another car that was also running a Vishnu tune. Took about a whole day with the help of an outside party to adjust that dip. It's evident this is a tune issue, the huge dip doesn't exist on the stock tune. In fact, the stock tune shows a progressive line when compared to mine.

Whats Next:
I hope that @Shiv@Openflash finds a fix for these two issues: no power in the 1500rpm range and MASSIVE dip at 4700rpms.

I dont know what dyno you guys are using -- I'm no professional, but I think a day on the MaHa would really help out.

Over and out..

The above goes well beyond "simply wanting to share my (your) experience".

haha, nooo. The car is plenty fun at 200 whp. Especially if you start tracking more, stick with NA for a while until you really get a good handle of the car. Don't be like me :bellyroll:

My gosh, sorry if my words came off wrong -- didn't know the butt-police were out in full body armor. Let me go back and correct that for you so you can pleasantly go about your day, jesus.


Take a look at all other dyno sheets you've seen. Most start at the 2000rpm range or higher, the MaHa starts around 1500. Other sessions may run for up to 15 seconds, the MaHa ran for longer than 30 seconds. What these factors play in real world situations, I don't know. If you can explain it to me, please do. If YOU can tell me what's wrong with my car, then do.


I've said in my posts that I'm more than happy to delete this thread once Shiv and I can figure out what's going on. I'm more than compliant to do what needs to be done. Rather than read through the entire discussion, you nit-pick on whatever gets you off. You remind me of people I don't like.

It's all good guys. OP and I will be meeting up to check out his car. It's a happy ending for all :)

How's your Visconti tune? Or is it delicious now?
