OLD ACTUATOR VALVE WILL CAUSE BOOST SPIKES ECT.

[Kappo]

i got my blitz dual spec r done while i was getting my tune done to my pfc, it holds boost all the way to 7200 rpm for me, dont feel much drop at all, but that was on a highflow turbo.

so.............what is your gain setting for your blitz dual spec r? I set my one at 20 and it go up to 0.88bar.

Well.... your one is S13? I have no issue about the bar drop. I am using Blitz Dual SBC Sprc-R. May be some of the plastic hose has broken so that it can not hold to 0.90.

on my chaser not s13

old thread. i know

but gain should be fuck all.
little fast spooling turbos like these should have gain set somewhere between 3 and maybe 7, so as said before 5 is good.

if u set your gain to 40+ u will see no gains in spool time, and in normal situations would spike to the shithouse.

as other people have said tho, 100's with there ceramic "high effeciency" turbo runs out of usable puff at around 1bar. any extra boost will result in minimal power gains and every chaser i have driven / been in will have a noticable boost drop on the dyno (this is with aftermarket dump and no cat)

for those who are running spastic high gains, the only reason u arnt seeing massive spikes is because the turbo is maxing out.

ill prove it. go and unplug your actuator line going from the turbo. "unlimited" boost on chasers really isnt unlimited
