LOL. That Tornado may actually work. I won't buy though because I'm not sure.

 

heyy i know people with 600 crotch rocket engines on race cars and they dino them stock get aroun 100hp at the rear wheels the guy playes twith the mapping and dynowed it again and got 125 hp at the rear wheels. this is my car with a kawi 636 cc 4 cylinder 2005 engine duel injection running on methanol. the car is a 2007 p3 600 micro sprint the aker of the car is on the side.heres a vid of mine.

so it is possible to gain tons of power with the fuel injection but i have a dyno jet box that is a few hundred dollars and is adjusted in every 500rpm with the injection and sees were you throttle is to tell how quick you snap the throttle and everything to get the perfect air fuel micture for the perfect power. i have never had mine on the dyno yet the prev owner did that but every engine is different and you cannot but mapping you need to get it put on a dyno and some places found out how to program a stock efi box on a dyno to save you money so you don't need to buy a dynojet power comander box. you will be beter off finding a guy that will hook your atv up to one and paying him 200 and getting a perfect running more torqe wider power band and more hp especialy if you put a k&N air filter on it. after you do anything with fuell change, air filter style change, air box change, eghuast change, you must re dyno to get max hp

 

Hey Frank, on those Tornado adapters.
I have a family member that put one on the Family Van.

It makes it "sound" more powerful. It does add torque in the low end, helps it to get moving better.
It does increase horsepower up on top. A noticeable difference in passing a vehicle.

However, it did not make a change to the gas mileage that was noticeable.

So I would offer, that it gives you a little boost, that may over time show a slight decrease in Fuel costs but not 10% or even 5% that they could see.
However, it does make this 12 passenger (big family) Commuter van get moving better and behave better at speed for no real losses.

That could be considered a plus, just not the claimed numbers.

 

Thanks. It might be worth it over the life of a vehicle then, but not pay for itself in months.
