Default Don't get mad! Where should i start?

You can read my sig, almost nothing done. the guy i bought the truck from said he installed 30 or 40 horse injectors but you cant ever trust nobody. i forgot to put in my sig but i got gauges: pyro, tranny temp, boost. wot it gets 28 psi. in neutral it will turn 31-3200 rpm's but it stops fuelin at about 2400 while driving. do i have a 3000 gsk or no. it puffs no smoke at all. i like some smoke but i want to get power. i will slide my fuel plate and starwheel. does moving the afc housing help. if i dont have a gsk kit how do i adjust it up a lil. i want power without tearing up my stock auto tranny. everyday driver hardy no trailer pulling. what exactly should i do for free. thanks guys

You're on the right track. Slide the plate and housing forward, and turn the starwheel and you'll get some smoke. Of course remove and grind the plate profile and you'll get a LOT of smoke, but sacrifice the stock trans.
No GSK, thats what they do when stock. You can turn the spring locks in a couple clicks, do both evenly, and that'll let it spin a little faster, or just get the spring kit.

Where is the egt probe? It should be in the exhaust manifold (pre-turbo) but may be in the elbow or downpipe (post-turbo). If pre turbo 1250* is the line you don't want to cross for more than a few seconds. If post turbo about 950* due to the exhaust being cooler after the turbo. The reason is that aluminum starts melting at that temp, and your pistons and turbo wheels are aluminum.

i slid the afc housing all the way forward ground the fuel plate to a 100 and turned starwheel all the way then backed it off about 1/4- 1/2 turn. it smokes a lil bit now but my boost level is down from 28 wot to now 22 wot. and the damn thing stays on that fuel stop level2500 rpm at wot. it revs in first gear then by the time it shifts second gear already is 2400 rpms it never really drops any rpms. i can feel and hear that its more powerful but for me i feel like this was a waste until i get a gsk kit. how does everyone else go about all that?

Well, on a stock auto you're gonna blow the trans out of it no matter what you do. With a Billet TC and a new HD Valve Body, you can slide the plate all the way forward, slide the AFC forward, block your wastegate if it isn't already, and throw in a set of mild injectors. You never said what year your truck was, and that makes a big difference in pump output.

Some do, some don't... Mine just let go one day as I'm cruising home from work. Something broke, got into the pump, and trashed it so I had no line pressure. Don't ask how it got through the filter, cause I don't know, and either did my trans guy. Anyway, watch your temps, they'll show you a little bit of info, but now a whole lot.
