Default Newbe Question

I have did just about all the Tunes (?) That i read about on here
Turn fuel pin 90, turn star half turn, And turn in smoke screw.
I still have no smoke or Any more power then when i started..
Only thing i have not done is full power screw cause i can not figure how to get it out
Question is why no extra power or smoke ? is there any tips on getting full power screw out ?

ok first off man you dont take the power screw out you screw it in a turn or 2 or 3 just be sure you have the intake off so if you incounter run away you slap a 2x6 on the turbo so it kills the engine because a 20 year old diesel ingine turning 5000 rpms wont do you or your truck much good! secound i did alot of mods to my truck iwthout much power gains the best investment you can make as a 20 dollar 3200rpm gov spring and prolly a fuel pin from mnh! about your gauges you are most likley getting a pryo and boost? thats my best guess for the boost gauge you can tap in on the drivers side under the intake elbow, for pyro depends if you go pre or post turbo i prefer pre turbo most guys go post because it saves your turbo if your pyromoter sensor breaks, pre turbo is the accurate reading though you find the center of you manifold about 4 in away from the turbo and with the truck running and grease on your drill bit tap the hole the truck is running so it blows the shavings up and not through your turbo and the grease is for the shavings to stick to or you can take the turbo off and just do it that way it depends on how much time you have hope it helps if you need a detailed walk through i can pm you one or look on the youtube

Smoke should be an afterthought..... lets make power first.

look in the sticky section on how to turn the pump up its a good read and x2 on the not worring about smoke with everything i have done i have my pump tuned and i hardley blow any i mean if im at stand still at a red light i can butt it isnt anything to worry about when you se guys just rolling coal i luagh because usualy the have a turbo kill switch on the newer trucks or no mods and their stock trucks pump maxed out do it right the first time
