well my dads 97 was rolled and totalled off hes got a 98 12valve now and we just put the #11 fuel plate in it with an PDR hx 40 turbo and the fuel plate is all the way forward, its got autometer guages..the turbo just doesnt seem like it made a difference,, it will boost to about 37 or 38 psi then stops,once in a while it seems like it just doesnt build boost very fast after 25psi,, i was wondering how to adjust the wastegate for more boost, but along with that the egts are already fairly high going up a hill with a full 100gallon tidy tank and dry box egts were able to hit 1500 and its blowing a fair bit of black,...my dad still wants to change the plate out for a #10 or get ddp stage 2 injectors,but i think that he has enof fuel right now for the hx40 or will the hx 40 handle more with the pump being tuned right, because it says the turbo is good for 425hp and i really dont think hes at 400 yet.

 

check for boost leaks

 

havent found any boost leaks yet...how well should an hx40 be able to handle an #11 plate full forward with 4inch exhaust and a afe stg 1... also how do i adjust the boost to around 42 psi..do make the rod longer or shorter.?

 

I have to ask does the truck have a GSK in it cause if it doesn't thats the first thing i would do ASAP

 

no we have a 3kgsk sitting in the shop for it just havent installed it yet...

 

my bet is your defueling before you are able to build boost put the GSK in and you'll notice a difference I promise

 

I think a stock gsk starts to deruel around 2200 rpm, I know my 3k gsk starts to defuels arround 2800rpm and won't pull past 3100rpm on the dyno. Have you moded the afc yet this will help as well?

 

ok im going to try and put the gsk in there today but as for the moded afc now we havent done that yet..i will look in to that more and try understand how to mod it.

 

Its really not that hard to do this might help ya

I did the washer swap, ground the afc foot, turned the pre load screw, and moved the afc housing full forward the results are in my sig
