Power FC is my choice as youdon't need to change this ECU from low mods to high spec 600hp type set-up.
The PFC gave an improvement from low to top revs, fatter low to mid and bit better on top end on dyno. Full exhaust, intake and natural boost increase to .8 bar achieved by "efficient exhaust flow in intake". Boost still at .8 bar.
GTS-T was doing 140kw@rear wheels from 122kw "stock everthing". Dynodynamics was not in "shoot-out mode" to get a closer and realistic figure "on-road power".
Mods after as follows:-
The stock fuel pump was marginal on it's flow which is less than .5 litre return to tank per minute. Upgrade to APEXi fuel pump for volume at dyno tune. Power now at 155Kw ARW from previous 140kw. At this point boost is at 1 bar.
Added APEXi GT-Spec Front Mount intercooler for cooling, AVC-R boost controller "excellent" holds boost steady all the way to top end "no boost fade"and Z32 90mm air flow meter to increase flow signals. Car is at 175kw at 1 bar boost.
Added custom Garrett T28 roller bearing about 400hp, 600cc injectors and cams set with APEXi cam gears. Got 220+kw at rears. Stock engine internals.
Must get a good tuner for this ECU. APEXi Laptop tuning highly recommended.
Cheers!
