thanks in advance
Like others said, use a search to find more detailed info, but here's what I would do first:
1)
Buy a DataMaster cable and software. Before you jack with ANYTHING, do this. This will prevent many headaches in the future and will still be usefull when you start modding your Ty (big or small). Make sure your knock sensor and 02 readings look normal (0 to very small knock count and O2 readings of 800-900 for WOT). If the O2 readings are low, check you fuel filter and fuel pump. My pump was shot at 47,000 miles.
2) Check you IC pump for flow. The upper IC core should be only slightly warm at best (mine is usually cool) after some hard driving. Mine was shot on a low mile truck. If it doesn?t work, check the fuses and replace with the Johnson pump if necessary.
3) Hardwire your IC pump on with the ignition switch turned to ?On?. Run a jumper wire from the yellow wire on the IC pump relay to a ground will do it.
4) Install an aftermarket boost gauge. The stocker is a sick joke. I like Stewart Warner.
5) Check you rear brakes. They should hold the truck without creep to at least 5-7psi boost. If they don?t, do the basic SyTy rear brake upgrade (larger 7/8? rear wheel cylinders and larger rear shoes). It worked wonders on my truck without messing up brake balance or ABS functionality.
6) Manual boost controller (set to 14psi). My stock boost controller was a little flaky. Some guys may cringe at this but I really like the old ball and spring boost controller for a single stage of boost. Even with a stock turbo and without a cat I have no problems with boost spikes or creep now. If you go with an ?Ultimate? or equivalent ?chip? later, you may want to reuse your stock controller.
7) Install an adjustable fuel pressure regulator. It will help you tune WOT to a certain degree and will help down the road with more major mods.
8) Install a Racetronix fuel pump kit. They are easy to install and move quite a bit more fuel than the stocker. My stock pump was shot when I bought my truck. The DataMaster had O2 readings of 100 at WOT under boost (VERY lean). The Racetronix kit fixed this completely.
I hope this helps. Good luck.
