my mods are cai, tb spacer, no cats, hp tuned by virgil, and a 125 shot
my goal is to wax some lighning *** on the 1st and pull into the 7s in the 1/8th

 

I say you consider a smaller cam, built tranny, stall, gears, and tires for traction. running nitrous through the shifts will kill that transmission. 7's in the 1/8th is moving pretty good for a ext. cab with a 4.8. dont forget to run colder plugs for juice and make sure your tune is spot on.

 

i run tr6s and the tune thats on my truck was also on a truck with a 4.8 that went 7.40 on a 225 shot on the stock tranny and motor

 

you have the same exact tune as someone else with someone that is running considerably faster than you with different mods im assuming?

 

his tune is of course a little different and he did his own tune bc he is a professional at it and he was there when virgil tuned my truck and he was tellin virgil what to do

 

so, youre running all that through the stock exhaust?
at least put some headers on it to help get rid of all the extra exhaust youre going to make on that large of a shot.

cheaper isnt always better, and everything is different.
Hell, youre trying to get a 4.8 ecsb quick? Im trying to get a 5.3 ecsb Z71 quick. Its not easy, and there really is no fast track to it.

That 4.8 wont last long under a 150 shot. Get ready to visit the junkyard engine shopping, or to do a rebuild soon.

that cam is also not a nitrous cam. Its madfe to be a mild cam for an Fbody or vette.
There are MUCH better cams out there for trucks.
try to vinci trucker cam, or anything really with more exhaust duration than intake, to help relieve the pressure.

Also you say he is a professional? is he like wheatley, and have his own business?
how do you justify callign him a professional? sometimes you just get lucky, lol.
