Enjoying tomorrow's success today
See what I did there?
Anyway, for those who don't know, Pigpen is a 8600 GVRW K2500. 4L80E, 5.7 Vortec, 3.73 gear's, 265/75r16 tires. A basic truck.
Pigpen, runs like an utter turd off the line, and will not spin a tire, even in the rain. It ran the same last night with one plug wire pulled off it. It does pull cleanly to 5600 or wherever it shifts at at WOT, but the tip in, just sucks.
I understand 4L80's have a taller first gear, I understand I only have 3.73's, I understand it's not a race car, I understand it's just a small block in a 3.4 ton. I'm not asking for flames out of the tail pipes and all that Fast n Furious BS, I'm just asking for some off the line, which, IMO, it should have something there.
Thing's I have done so far,
New shift solenoids and wire harness inside the trans
New Autolite XP 605's gapped to .055
New Jeg's 8.5mm MSD copy wires
New air filter
Gutted the cats
None of this has made a difference in the throttle response or low end the truck has. It has 58 PSI of fuel pressure, it is not popping any codes other than for the missing cats now. I do not know if it has an upgraded spider, the previous owner say's he never did anything with the injectors, and was truthful about everything else. He owned it for 10 years, so I'm going to say it probably has the stock poppets, even though it really looks like the intake has been off it before.
So, if anyone has any ideas, I'm all ear's. I just ordered a new distributor today, I'll do the ICM and coil after that, then I guess I'm onto the spider.
