91RWHP and 96RWTQ....

Coupled with the new intake that just came out, I'd love to see some 114-115mph traps in some good air.

I'm sold...

Which intake are you talking about... the new AFE Dual cones?

It's clear that we now have two different theories as to how to control boost. I do recall the Vishnu folks calling bull$hit on Terry's theory of how it could be done. Looks like Terry may have found a way of doing it that is safer and less spike proned then the Vishnu method.

I am not trying to start crap, I am just giving full disclosure so people can make a decent comparasion. I didn't mention it at the time of that dyno with the PROcede because it was a beta map and I didn't think it was right for me to mention something that wasn't going to be released to the public.

I can almost guarantee you that people will not see that much power gain from those AFE dual cones.

Two different methods from two completely different systems. Both have their advantages and disadvantages but in the end the JB3 fit the bill for me.

I am going to mention this again, lets please keep this thread about the JB3 and not about the PROcede and its differences compared to JB3. If people would like a thread about that please feel free to make one.

You have made and continue to make some fantastic contributions to this board but it looks a bit disingenous when you decide to disclose this stuff after your V3 is sold. Perhaps we can get some clarification in a separate thread.

I was beta testing a map at the time of the dyno and as such you don't disclose the errors or irregularities that you see to the public. This is known by most beta testers....

Just got done running this thing in 104 degree heat, still silky smooth with no boost spikes.

Did you notice boost dropped from cooler weather, throughout the rev range? I remember hearind that AIT correction would lower boost in high temps.

Yes it did get lower. I didn't see anything higher than low 14's yesterday at WOT. On the dyno that day with good cooling I was seeing ~15psi, so basically with the increased heat I am seeing 1psi less of boost.....
