I think the norm is to add 3% from 4800 all the way up, the anotehr 3% from 5000 all the way up, and again at 5200 up, all the way up passed your rev limit. This method made mine pretty smooth once the MAF went flat.
Mine flatlines at about 5400 I think it is. I can't remember for sure though.

I did the same thing on the PE table. I've YET to figure out a better way. Hptuners is suppose to be coming out with a way to extend the VE table on to 200kpa and even 300kpa in the future. If/when they do that, I'm going SD if I still have the blower by then. I bet it would run tons better and a lot smoother that way.
Do you have a hesistation from idle with that thing? That's in the VE table too BTW. That's supposedly VERY common with the SuperChips tune.

Here's a link to a thread that shows some screenshots for the 3bar tuning. It's on HPT's site.

congrats on the blower!
how in the heck are you maxing that maf all ready? and at that rpm? thats very impresive.
i have always gone with the 3% increase for each cell from the max point up. it gets you prety close. thing is on a cold day or a hot day you max at diferent rpms.

Thanks guys. I was worried that I'd have to spin the Radix too high to make good power. I think I'm going to be very pleased with it. The real test will be when summer heat kicks in here in Texas.
The first time I looked at the log and saw the MAF go static at 5000 rpms, I was shocked. I was flowing a peak of 47-48 pounds NA before the blower. I never dynoed but I'd guess somewhere in the 360-370 rwhp range N/A. Old N/A logs show a peak of 39 pounds at 4900 rpms where the radix hits 59.9 pounds.
Well Jim, I read one of your posts from the past saying you added 3% like that. On my 2nd tune, I followed your lead and added 3% to 5000, then took that number +3% more and filled the next cell, and so on... I guess it didn't work. I'll start it over and make sure I have it correct.
The truck has developed an idle issue. Its been fine for over a year with the cam, but with the blower, it stalls, bucks at idle, and dies. The radix has a vacuum regulated bypass similar to the whipple. I'm wondering if the cam lope is tripping up the bypass. It idles better with the higher speeds when the A/C is on. I'll bump up the idle and mess with idle airflow some.
Injectors - I'm worried I may be out as well. I'll log pulsewidths next time. They are the Radix supplied delphi marine 42 pound injectors. I already had a set of them installed because I maxxed out the stock ones N/A. I really hope these 42 pounders are enough for me, they were so easy to tune.
