I'm Awesome
I'm not doing a tune ive bin thinking of buying a HP tuner as my truck Is 98 and I could make money on the side working on freinds trucks. My truck is a 98 Z71 Silverado with 350 000km on it it was gutless truck from factory it's even more gutless now with age. All I would like to see is more mpg highway my engine finally came on the other day it to buddy's shop asap and it's coming up fuel pressure but when fuel gauge is hooked up fuel pump is still well in spec so we're set it's the spider injectors and or the fuel pressure regulator. Disconnected the battery for few hours no more engine light I'm sure it'll be back I ordered a mpfi AC Delci mpfi with regulator will be installing it over the Christmas holidays. Hope to gain some mpg and some power it's embarrassing trying the pass I drop it to the floor and it just falls on its face takes forever to pass anything I'm sure not a fan of these vortecs my 5.7 TBI was way better powerwise and mpg.5.7 vortec to 5.7 TBI swap
