Anybody experienced any surging problems with APR? Just wondering if all chips experience similar problems, or if APR has had more success in this department. I haven't been able to come to an appropriate conclusion with the posts in the archives.
I noticed (according to them) that they don't have many versions, just 1 and 1.1 the octane specific programming. Up, and GIAC have gone through a few versions. I guess this means APR's program has been pretty good from the start?
if anybody has block 115/120's of apr chips I'd appreciate it. I am interested specifically in the 91 octane program.
