thread jack: why aren't you on AIM homo?

 

you need your truck timed. just put 4 k in mine, once it got to 2500+ it would pop like i had glass packs on my truck. timed it, works good

 

hell mine still pops at 2500 even with 18.5* timing

 

hhhhmmmmm I wonder why yours pops... Maybe we are on to something here

Who knows

I now need to see with the truck warm to see if it clears up or not and go from there. If anything I also need to get these springs done so I don't have to worry about the valves hitting while I am trying to get this figured out.

 

ya, i went with the hd vavve springs but maily because of my exhaust break. i can relly notice the poping doing boosted launches

 

Well tom I will warm it up go for a drive and give it some revs and maybe I can make a video of it and see what I find out. Remember having a automatic I can't rev it out like the manuals to see if it will still miss

 

lock it in second, get on it till it revs out, if its timing it willbe bad through there
or at least mine was

 

I agree I think you need to fix timing and check fuel pressure

 

ya cuz i got 4000gsk installed in my truck monday. and it actually lowered my idle almost 200 rpms down on its own. i have 17.5 timing. and i notice no problem with it missing. and i can rev it up as high as i want, so far i've only gone to 3300 but it gets hot.

 

Hmm, i got the 4gsk, it does not pop. i have the stock timming too. I am thinking that these trucks all react differnt, i just put the 3gsk in my buddies truck, it worked great and about 3 weeks later it started to act up, it will rev fine, then it will start climbing byitself, i don't know what the deal is but i do know it stopped once i set the idel to a lower thanb recomended postion, like 600 or something. These pumps are strange.
