Hey guys I'm a newb on the site and did a little searching before i posted but couldn't come up with the answer. I bought the truck from a dealership in NJ about 2 weeks ago and have had a few probs with it. The guy who had it before me did some ghetto install hack jobs. The wiring is all messed up, the guy had neons inside and out which have since been ripped out by me as soon as I got the truck, and the HID's he had in it don't fully work.
All that adds to my concern about the hesitation. I have an autometer boost gauge and at WOT it reads 14psi, but the truck hesitates a lot, and the power keeps coming in and out. At 95% throttle and about 11psi its fine. Any ideas? I took it to the delaer and they said they didn't work on superchargers lol. So I'm taking it back to NJ toamrow to sort out the HID lighting issue, and I'm also going to bring up the hesitation probs. Also what is the stock boost level set at? Any help would be great, just so i can have something to go off when I speak to the dealer tomarow.
stock boost should be around 6-7 psi, sounds like yours has a aftermarket 6 or 8# pulley....which is fine if your tune is good, if you hear any pinging, get it tuned! pinging is bad...real bad!
Its not detonating, or pinging, at least I can't hear it if it is. Is there anyway to tell which pulley it may be. The 6 and the 8 are both lower pulleys correct? Any other ideas of what it could be short of getting it tuned? Thanks for the help.
I don't know if you got this figured out yet. Since you're in NJ, take it to JDM in Freehold. They have some good mechanics over there and they specialize in Lightnings. No doubt they will be able to figure out the problems and even dyno tune it for you.
I have an 02 Harley with #8 lb. pulley, the tune to go with it and a few other extras. I burnt the tip off of a plug at 140 mph. The truck idled fine, accelarated ok, except under wide open throttle. I know it's a job, but I would check the plugs. I found the bad one on mine, it was the last one I checked.
