Stepping my IX up for 91/E85, looking for final preparation suggestions
I'd rock the red because it comes up so well on a 2.1 but I've got a biased opinion 
I feel the red is well matched for these cars as a do anything turbo and be fun around town, auto x or road course.
A 2.3 MHI black would be alot of fun also at moderate levels.

Based on my experience dealing with RR they wouldn't let him leave with an unsafe tune. E85 is a hell of a drug. The true AFR of E85 at a Gasoline 14.7:1 is ~9.85:1 so at a WOT ~11:1 your at like a 7.32:1 you can imagine how much alcohol you are dumping in there. This really helps with those blow dryer like conditions.

Hi Tim, I am worried about that too. I did a bit of comparing between dynos and noticed that these Dynapacks reads torque differetly compared to others. These torque numberd appear high on this dyno compared to others. Not sure why since they're usually a factor of horsepower. I should ask for a detune for safety.
I don't plan on running this 71 long. I have a Red and Black sitting in my living room. I'm thinking Red next on my stock bottom and save Black for 2.1 stroker. What do you think?

So I should use Red on stock bottom and for 94mm stroker? Both are MHI hotsides.

I did and he showed me actual dyno graphs of each. I recall peak torque for Red cam in about 4300rpm and Black was about 4800rpm on stock blocks. I'm looking at about 1000rpm difference for Red and 2000 for Black. Red is tolerable but Black will be tough to get used to.

Well then at this point it probably comes down to your use case / preferences, which is pretty hard to for anyone else to figure out. I vote drive it with the 71 for 90 days to solidify your impressions then swap it out and see if you like it or not. Beyond what the numbers on the screen say, as in how you like it in your use case.

Having a hot spare is never a bad thing. If the red needs to go out for service or what ever you have something you can throw in and have a tune for it ready to go. If you decide to stick with the Red that is.
