Well I just got finished with my installation of some goodies from cfm-tech. I installed the tbi power plate, injector space, power charger, adjustable fuel pressure regulator and guage.
Everything came with instructions and the instructions were pretty straight forward and easy to follow. I did run into some problems however. I had a couple fuel leaks at first, but some double checking and re-tightening helpd solve that. I had to re-mount the dist. coil because the in line fuel pressure guage was in the way. It was also very hard to get the guage to be in the right place. As it is now, its upside down but thats the only way it will go so I guess its fine. The only major problem I have with the kit is with the adjustable fuel pressure regulator. You are supposed to be able to turn the thumb screw while the regulator is still on the truck. This however is definitely impossible. Due to the screw being under the tbi and touching a hard metal vacuum line fitting, I am forced to tkae the 8 torx screws out of the top of the injector pods, and then completley remove the top of the injector pods and the regulator to adjust it. Its not really that hard to do, it just takes some time, and its a pain in the ass to have to do that every time I need to make and adjustment. I recommend that cfm-tech change the design on this to make it a little more accessible. I also had to re-adjust the tv cable to get the transmission shifting properly again.
Now, these few problems are significantly outweighed by the power gain. I notice much more throttle response and power throughout the entire rpm range. All of the spacers and whatnot provide a "sucking" type of noise, that pssss's when it changes gears (almost sounds like a supercharger). Before when in a grassy field, if I floored it, it would burn out but not for very long before the 37's grabbed and sent me on my way. Now, it will pretty much sit indefinitely clawing large trenches in the ground. I am very pleased with the power gain.
Due to just being finished, I have not yet been able to determine how much more mpg I will get. Im hoping 3-4 mpg, but my foot will be in it a lot more now so who knows. The install would have only taken abuot 4.5 hours, but ended up taking more like 6-7 with all of the dificulties. But, the power was worth it.

I need an adjustable regulator. My motor likes to break up a little at highway speed and backfire when I clutch and shift. If I don't speed shift it will be pop throught he exhaust.
