I have a Impulse Race system on my O8 Nytro it has the GT2871R Hydrid Turbo the throttle response is absolutely incredible had a 06 turbo apex and a 700 turbo Dragon and this thing absolutely impresses me. Also have a 162 track Vanamburg tunnel and other goodies on it. The system you chose is up to you but get with some one who will give you service. I rode with Dustin and Cody James Sunday and Cody rides a Super Charged Nytro, it is one of MPI's kits but I think Cody has an attitude control box on it. He is running 18 lbs of boost and I am telling you that thing rips. There where 6 of us riding together 5 of us had boost and Cody's sled was pretty impressive. Just pick what makes most since for you as long as it's boosted, but get with someone who knows their stuff. I don't know where you live but since you are Riding a Yammie I would give the boy's at Outlaw Motorsports a call. I have had a couple issues with my Nytro since the Impulse Race system is so new and there aren't alot of them out there, he only as three of the Impulse race systems out, mine, his, and another up in wa. don't remember where, Twisp I think. But he has a ton of Turbo and supercarger sleds running out there. Dustin has treated me like GOLD and I am nobody special just one of his customers. Their customer service is 2nd to none and I believe when it comes to Yamaha's Dustin is the go to guy in the Northwest.
Give Dustin at Outlaw a call and talk with him and he can help you make a choice that is right for you, and if he is involved you will be happy with the results.
Hope this helps- Pat
