TBI conversion.

You can go a couple of different ways with the chip. If you don't want to modify the ECM with a new chip socket, you can still get the original style chips burned. If you think you'll be learning to tune it yourself, I'd go with the new socket, but if it already runs pretty well and you just need minor changes, just get a stock style chip burned.

Do you already have it up and running? Are you using a VSS or EGR?

Yes, I am using the VSS, and EGR, although the EGR needs to be replaced (vacuum leak), and yes, it is running, but I'm having problems with highway speeds, does good up to 55-60 mph, then it loses power and i cant get over 65. 60 to 65 in 10 seconds sucks.
I may have problems on the fuel pick up, as i am using the fuel pump, and sending unit from the downer truck which had a 50 gal tank, and the Blazer has a 20 gal tank.

Just working the Bugs out.
