I did't know V6.32 exsisted, I got 6.2 as a beta from the local Accel 
dealer a month or two after I bought 6.0.
I beleive the utility can only be accessed in online mode from the 
global menu.
Does swithing to TBI mode make the inj fire at twice the rate?  if so 
then 4 of your inj would = 8 TPI inj.  just accout for the cu.in. 
diff and the 22 VS 36 lb/hr

455/350=1.3  so multiply map by 130% for cuin diff.
22/36=.61   mult map by 61% for inj size increase, if you have half 
as many firing twice as often.

Both of my systems are on chevy's firing stock TPI intakes, so I 
didn't have to do all this.  Although my maps look nothing like the 
samples provided by Accel.

If any of this looks wrong let me know.
