pretty easy to program out vats and stuff, didn't play with any maps yet.

Final mounting for the pcm will be the pass side where the evap can would be. I unbolted the plate that the evap can sits on and mounted it there. I will have to extend the wires about 8-10" but I see no other way. It isn't that big of a deal. I'll get some pictures someday.. Right now the car is on standby.. The TelCo that I work for has just gone out on strike .. so I'm busy there.

would i be able to plug up the out let line under the throttle body? i'm using my 3rd gen radiator and there is know where to hook it up. the drivers side hose does not have the line going to the throttle body. and also the inlet and outlet heater hose's are opposed of the 3rd gen (my 91) right. sorry about the job

Told ya bud, get a 93 Z28 upper hose and it already has the fitting for the throttle body on the radiator hose. What you can do alternatively is do the throttle body bypass:

i bought a 93 hose and it was too short i went to three auto parts and nothing. so i bought an adapter and connected throttle body outlet to heater outlet. what do you think. did you get your car runing?

Whoah, how can it be too short? Let me go outside right now and i'll take a picture.... Engine is running perfectly. I just put the transmission in but tourque arm, hydraulics, and driveshaft are not hooked up.

the one i bought looks now where near like the one you got. it was a short hose. didnt even have that smaller hose with it.
can you take a pic of your heater hoses. i'm gone try napa or car quest next. he man and your headers are they shortys, long tube. how do they fit? what brand are they?

Thats a 93 z28 Upper radiator hose and 93 z28 lower radiator hose, I got them from O'reiley's. Maybe he gave you some 93 v6 hose.

The headers are SLP 1 5/8" w/ 3" collector's shorties. Drivers side clearance was fine, went in without problems.

It was the passenger side that took me almost a day to get in because no one carried any 3/8 x 1" bolts and I had to use some hex bolts and the very back bolt of the passenger side was almost impossible to get to.

Yea man went to napa yesterday and picked it up today. did all the pluming work today looks real nice so far. I took the dryer out to see if the pcm will fit there and it looks pretty good in that spot. Turned my car on so a friend of mine can here it and when i hit the throttle it shut off so i guess i got to mess with the dam vats.

These come with a lifetime warranty. I'd rather program it out but this is an alternative.

I went to the chevy dealer and they told me they could not delete vats. he said the only thing they can try to do is match my key with the pcm but i have to bring my car in. i told them the car was apart he told me that all they can do. i also called around and nobody can do it. so i ordered the bypass maybe that will work. any thing on the vacumes
