ok, the 215's seem to run better @ 19mm of rack. So I would put your afc back in and tune it, set the plate to 19mm of rack travel, put that 4k gov spring kit in, and spend your money on a better set of injectors.

prob right arround where your at now ... what boost numbers are you seeing? also have you hooked a drive press guage up?

drive pressure gauge? where does that hook up too?

captain_stabbin's Sig:

94cummins, 4"turbo exhaust, fuel plate, airdog 165, kdp, quickspool manifold. gauges, boost/egt..head studs, 4gsk, 60lb springs.

it measures the press in the exhaust manifold. Mine will be mounted where the egt probe used to be.

youll need some copper tubing and an inline filter

makin 40 to 50 why do i need a drive pressure gauge

itll help you tune

what should i look for

you need to check your drive press, that 65mm exhaust wheel spools quick but chokes out up top.

When you read your drive press you compare it to your boost numbers. the best ratio is 1 psi drive to 1 psi of boost.

for example if you make 40 psi of boost you want your drive press to be 40 psi or less, and with that turbine wheel I bet its gonna be high.

I read somewhere that with an hx 35 when your making 35lbs drive pressure was over 60.

hum good idea where can i get one

its a boost gauge youll need copper tubing and a filter

If you want a better DV, get some .022's or .024's milled, more fuel, same heat as the 191's (the .022 might be a tad higher EGT wise then the 191's, 50* maybe). Put your AFC back in tune it and get rid of the 370's.
