Hi Guys
I have a GU4 with a ZD30 and 150000km. I have a minor issue with my EGTs and am hoping some of you have experienced this after like mods and can assist with the key piece of the puzzle I'm missing.
The vehicle has:
Standard Tyres, Rook Rack, Side and rear awning, roof light bar, high lift jack and shovel, ARB bullbar, winch, Narva 225 spotties (in bar), 2" lift, Dual Batteries, Cross Country I/C, dawes and needle valves, Full NADS, 3" exhaust with cat delete and 1 muffler, Roo Systems chip (was ordered with an economy tune but not convinced that the case), Lift Pump & spill line mod, Fuel manager water separator/30 micron filter, Full auto trans rebuild inc valve body upgrade etc, ARB Rear Air Locker, Rear Drawers, 40lt engel,
At 100km/h not towing and not loaded my EGT's are 350C and when I put the caravan on (17ft 1986 Jayco Poptop) it jumps up to 450-500C (depending on the day, wind, etc) My bail out temp is 550C so I dont have a lot of room to move when towing. We normally cruise at 90km when there is light traffic on the road and these temps dont drop much with the lower speeds.
With no Van on when I go to overtake a car on a flat highway the EGT gets to 550 rapidly and can go over 600C with ease (only did this once or twice for a split sec to see if it would stop climbing in temp which it didn't).
Since putting the chip on I haven't returned the improved fuel consumption I was expecting and am pulling around 13l/100 on a trip empty not towing.
Im not sure if I have an Injector issue or something else ive overlooked.
And advice or similar experiences appreciated.
Thanks Guys
