Misses, Sputters, Hesitates FOR OVER A YEAR NOW

OK, For over 1 1/2 yrs I have been fighting this wierd issue, sometimes I thought it went away, SOMETHING just isn't right. In the past I tried numerous spark plugs at all known gaps (7's and 8's), multiple NEW fuel pumps, new/known good AFPR's, COPS, good coils/wires, stock ignition and MSD, fuel lines and filter is good (changed/replaced/by-passed), different injectors, different MAF's, was DSMLink version 2/2.5 now recently 3. You will probably see in the log where it starts, it isn't rpm specific, but seems boost specific. WTH, someone just gimme the fix ALRAEDY PLEASE. all this was on TT111 Race fuel.

Probably tune related, maybe a boost leak. I was working on a supra a while back with similar issues and we had to completely re do the tuning and we found some weak spots opening up under boost.

compression test?
You didn't over look a boost leak test did you?

Did millions of boost leak tests, also plenty of compression tests (forget the numbers, but really good).
