Standing ¼ mile in 11.2 seconds at 126mph
that is good to me..... Vinshu is very very popular

 

a guy from around here had some problems with one of their ecu's though.

 

what kind of problem

 

prob a bad tune... You need to get a new tune after every mod . that is why I did all my mods and tuned it for that. If I do anything more I need to re tune the car. If you dont tell them EVERYTHING you have in mods it can render power. Also human error can set in and make a mistake that causes trouble, but same goes for any company

 

There are three major tuning companies that will tune your car. They are Vishnu, DynoFlash, and WORKS. Vishnu, from what I've heard and read, gives lots of peak power but at the sacrifice of a smooth power curve; their FLASH is also the most expensive out of the three. The DynoFlash usually produces a little less power than Vishnu but it's much cheaper. Then you have WORKS, they have a smooth power curve, allow the computer to control the boost (unlike Vishnu and DynoFlash) which is "much" safer and they provide a smooth curve throughout the power band. In addition, if you buy their parts they don't charge you for additional flashes in the future. Yes, I did get the WORKS flash so I will vouch for them of course....I'm just trying to get you headed in the right direction...
