I forgot to explain myself last time, so here's my thoughts on it: (not a rant, just an explaination) I'd like to here others criticisms and opinions
Timing is a good idea, 15-16* on stock HG is usually all it will hold.
A 4k gsk costs the same as a 3k, a set of valve springs cost $55. The 4k certainly won't cost you any power (the 4.5, 5k, etc cost drivability) Might as well have it even if you only want to use 200rpm of it. Remember the governor starts to defuel well before the rpms stop increasing.
The 2095 plug costs $15. 215 injectors have been used in over 500hp builds, 180s have made 450hp, and both can be picked up used for cheap. While delivery valves might help, they are not the most cost effective gain. The common build order is fuel, fuel, fuel, fuel, fuel, fuel, fuel, fuel, fuel, fuel, fuel, fuel, a little bit of air, fuel, fuel, fuel, fuel, fuel, fuel, and some more air. This leads to a lot of smoke (I don't like and give diesels a bad name which will bite us later) and excessive EGTs (also don't like, people often get mad about it because they can't use all there fuel, but whos fault is that?)
The fuel plate and AFC can be modified at home for free. But DDP also sells a budjet fuel plate kit that includes a boost elbow, plate, and washer for the AFC. Well worth it IMO

Adding fuel is cheap, but once you spend money on fuel first the next upgrade is always air. If you spend a little on fuel and some on air, you will be able to get a more balanced combo.
If you save some money on fuel you'll have enough left to get a larger wheel for your hx35 or even find a cheap hx40 (kinda like the 370s of turbos, cheap and kinda crappy but effective)
Being able to modify things yourself, and tune your truck well will save a lot of money and make lots of extra power.
