Oh I haven't even seen the new on yet... I thought he was talking about the first one. The one that started so much rice fest in America, that we could feed Japan for a decade.

I'll be thinking I want this tuner then look up another and decide I want that. I was first thinking JB4 because its cheep and good results. Then I got hooked on Procede V5 but as usual I started to find cons and it costing more. I don't know which is best so I figured I'll just ask what people are running.

What kind of tuner and type?
What hp gains did you get from it?
Pro and Cons to your tuner?
And how much did it cost?

P.S. Also if the money wasn't an option which do you think is the best for results and integrity?

It breaks down a lot of the details your looking for.

That 12% drive train loss is for MT, no? I would imagine that AT have a little bit more, like 15%?

330/(1-12%) = 375HP
example 2 (with Vishnu's PWM Meth kit)
Stock Map, with DCI 284/(1-12%) = 322 CrankHP
Vishnu PWM Meth Kit and DCI = 406/(1-12%) = 461 CrankHP

so Shiv's advertised 122HP gain is actually 139 at the crank
