Let me tell you that there is no way I would run a piggyback and meth injection on a car for a 15whp gain. No chance of keeping warranty and a lot of work involved in removing the system to go in for warranty work if you needed to.

Other tuners havenet implemented it yet likely because the gains are so small for adding a complex system like meth injection to your car. This isnt a turbo car where meth injection adds 75-100whp and tq.

No need to bash other tuners for not implementing something that is complicated and in my opinion not cost effective at all.
I am endorsing anyone who is doing something unique and different rather than the same tunes everyone puts out with some a/f changes, ignition etc. Nothing "special" about the vishnu tune itself alone without the meth componenent.

You are missing one HUGE thing however, especially for people in cali or arizona or people out eas in summer. Keep in mind the stock car on 91 pump and even 93 does not even make the standard 414 crank hp due to not being able to fully advance the timing in the stock tune. Then you take it in the summer months and you are way down on power.

Unless you use race gas to prevent some of this-its hard to even make the stock max power.

So a tune using non-race gas in summer will maybe net you 10-15 over what you otherwise would be making which is a lot less than the rated hp due to timing retarding.

The meth addresses several things. First it provides the ability for the computer to not only maximize advance stock but even further advance timing due to the octane boost by meth. Tunes alone without race gas/meth cannot advance even beyond the stock limits let alone further or the computer will simply retard it.

Also the meth itself cools down the air so in hot months this really eliminates the hot weather effect so the added hp from the tune/meth can be added to the actual power the car should be making stock rather than starting at a lower power from timing retardation from heat.

As far as warranty-proceed being piggy back is the easiest to remove in two seconds. Also can remove the meth kid easily. So no issue with warranty unless you are too lazy to remove it. A flash tune is harder to take off unless you go with a self flash system tool than its great.

So maybe 30hp is not much to you but its probably more like 40-50hp in the summer months which even 30hp is HUGE for an NA engine.

I applaud people that do unique things-if this was so antiquated then why haven't others done it? People spend a lot more on exhausts and pulleys and removing cats which do not give you near the same power.

To each their own-I applaud shiv
