ON 91 OCTANE!?!? I'm nursing a semi just thinking that you'll say yes.

all testing was on 91 octane with better results still to come on the C38 tune.

also please note that our dyno reads low...expect to see 20-30hp more on other dynos

the E85 tunes should yield spectacular results like never seen before

on the same vehicle, if the horsepower is higher at any given rpm...you can assume the boost is higher as well

Agree on the E85 bit...on the C30 blower with the standard pulley we're seeing gains of 60whp on an unfinished E85 tune...that's unfinished and with clutch slip.....on a low reading mustang. E85 is going to bring tears to the eyes of many on this kit.

All this news is music to my ears! Ps Brandon you guys get a couch and a radio for the waiting room man lol

Tears to the eyes of many especially since all that new power requires a clutch to make use of....lol

that can be slightly mis-leading, the c38 at the same boost level, say 9psi for instance, flows more air requiring more fuel and producing the more power because of it. the difference here is some thing like a gtx2867R vs gt3071r at the same boost level. more air = more power.

Where do I sign up for ots tune v2 and the idlers.

Thanks

Anyone get the r2 tune? I contacted KW about an updated tune and was told to contact Delicious instead.

What, you didn't like having a tranquil moment in our lobby listening to the air conditioning vents humming? I'll work on getting the TV back on the wall, just for you!

On to what everybody else wants to see, boost comparisons:

[Kakawate]

Actually it was quite peaceful. Thanks again @KraftWerks let me know when you want me to grab the header and maybe a oil cooler kit...haha. The car is loving this cool weather we have been getting, its only 75 in the desert! You guys rock keep up the great work

[Zach3794]

If the r2 is indeed the Delicious Tuning update, I have it We dialed it in over here on this one, and the increases over the base tune that Kraftwerks is displaying is valid.

[OjiGeorge]

And this is why I was wanting the C38... but most experts said no go :P Numbers look awesome! Hope the tune is safe for the stock internal guys. I want another 86 now. lol

[Zach3794]

Really? I mean the numbers look not that great for an upgraded blower to me. Considering low boost on the c38 is the 14 psi they stated. Don't get me wrong it's more power, but even KW said there's a long way to go with it. Maybe it's just since I make 333whp on e60 with the c30 at 9psi it just doesn't seem so impressive...also unfinished tune
