3.4 was old skool fuel injection that used only the MAP for the air monitoring. It was limited in how it would be able to adjust the AF ratio and how the fuel mapping worked. The engine determined the fuel requirements using readings from the MAP, TPS, RPM, and then the O2 sensor. This worked ok but it was hard to get ideal fuel ratios under all conditions, and since GM programed the computer to err on the side of effeciency you lose power. I have heard of the 3.8L OBDII computer being adapted to this engine and the gains are noticable. That requires adding sensors and other goodies to the engine. I think the guy that did it eventually did the 3500 head swap as well and made a really nice running 3.4L

Just ordered a bunch of LED's to replace ALL of my enterior lights! I'll let you guys know when they get here. I also plan on doing a write up on the gauge light swap for early 4th gen Camaro's. I know there is a lot of confusion about how it is done on the earlier 4th gens. So I'll clear the air with a detailed write up when I do mine. Hopefully it will be made into a sticky

 

Back in the 80 the MAF sensors wher so problematic we stopped replacing them and we swapped out a PROM to convert the computers into speed density (AKA no MAF). I can not remember a customer complaining about a lose of power.

 

I'm looking forward to that guide! I'd live to put some blue LEDs in mine!

 

It shouldn't be too hard. I'll do a detailed write up on it when I do mine and hopefully that will help some people out.

 

Nice would like to see some pics of before's and after's.

 

^Promised! As I will have pictures of the install process.

 

You dont notice the loss of power but you dont get the full potential of the engine. Yes I remember doing a couple of prom swaps (that is all they would let me do the master tech did the rest) I remember the TPI engines were really sensitive to this.

I installed my new door today! Here's what I started with:

Then I ripped that sucker off!



I put the new door on and ripped the guts out of it to swap in my manual stuff. I decided against power windows and locks. Too much hassle



When I was pulling off the side moulding on the new door, it peeled some of the paint with it so I bought a can of rattle can paint mixed to my color code and started spraying



Here's what I have for now. I will buff it out tomorrow

 

You should paint your front bumper like that! Just sand it then spray at it. I wonder how it would come out.
