I recently upgraded my turbo to an Hx35W with a 12cm housing. I'm running the truck non intercooled and non wastegated as it was before. My Truck is a 91 non IC truck. I also installed an M&H M2 fuel pin. I've dialed the pump in as much as I could while on the road. EGT's stay under 1000F most of the time, only briefly breaking into the 11-1200 range while going up large grades with my loaded trailer. I seem to have a dead spot down low especially when empty.
My steady state cruising EGT's are in the 700-800F range. Any suggestions as to what to adjust next or is it bigger injector time?
TIA
