even at light load, stock system will switch to twin mode above 5500 rpm.

quick way to sample 'simple' non-seq'l response at 3500+ rpm. (works with 93 stock ecu, not sure for PFC).

find clear level road, bring up to about 4000 rpm in 3rd gear. push clutch in and at same time don't let rpms drop, and raise rpms to 6K, then lower rpms to about 3800 and let clutch out. now decel down to 3500 rpm and then go wot. turbos will be locked in twin mode, and no transition kick will occur at 4500 rpm.

drop rpms too low (below 3400 rpm) and system goes back to single turbo mode.

with usual intake and exh upgrades, response for me was very good for this test. since my sequential sys is healthy, I'll stay that way, with 10 psi by 2400 rpm.

 

interesting...its too bad i have auto and it would be really hard if not impossible for me to feel this feature...im going non-seq soon anyway heh..
