fuel milage
 

i have a 98 12v it has always got 18.5 mpg and its wint down to 15mpg my turbo started to get some shaft play so i put twins on it and 5x.014 injectors from southern diesel 4kgpk from ddp head studs timmin is 16* this is still by far the weakest truck ive ever road in and get bad fuel milage to go with it i can baby it drive it hard it still gets 15 and the milage dropt befor i put anything on it so im sure nothing i put on it hurt it if anything i thought it should help it as long as i keep my foot out of it also all the filters are new and the lift pump is new what do yall think

have u checked for boost leaks? if u have an auto, is the trans slipping more than usual?

its a 5speed and it has a new dd south bend and check the keaks and came up with nothin how do you make a sig on here

Whats your fuel pres? And are you 100% your at 16 degrees?

yea im sure i have a adjustable pump gear with a key way were it want slip i set my timmin twice to 16.5 with a stock gear and it kept slipin and it pisst me off so now i got one that want slip and fuel press. is good 18 @idel 30 @ 2500
