I'm looking for a performance chip for my newly installed 3.4L. Does anyone have any recommendations of which company to go through or how their 3.4L chip performs? I already contacted the Fiero Factory, they wanted to drive it, but I live too far away, so that is not a feasible option.
I've been looking at Westers Garage and Dennis LaGrua's chips.
When I was going to get a chip burned for my 3.4 I was going to go to these guys: http://westers_garage.eidnet.org/scprice.htm I talked to them on the phone and they were very enthusiastic about helping me out. They do every chip custom, little pricey, but they take every mod into account.

I had my 86 GT out to see Ed Parks several months ago---3.4l from 95 camaro--- Jeremy out there (I beleive) is the chip guy---but how could they program a chip for a car without analyzing the car first? Anyway, when they tested my freshly built 3.4 with mild cam --they said it ran perfect and didn't need a chip. They burned a chip for Raydar on here for his 3.4---
I'm also building a 3.4 right now and getting a custom chip burned. I'm going to use winaldl and then send the data to Darthfiero ( http://dtcc.cz28.com/ ) to burn me one. I feel that a custom chip burned for your engine will turn out a lot better than getting a chip that is supposed to work for all 3.4 swaps. We all usually have different mods done to the engine which would require a different chip. (i.e. injectors, cams, etc.)
WinALDL? I didnt think the output was good enough to base a chip on. The refresh is so slow & the O2 sensor range is way to narrow. But, I suppose its better than guessing, and better than a stock chip. Let us know how this turns out. Anyone have any unused chips for a 3.1? (pref 2030 cam, no EGR, 17# inj)

Yup, Jeremy burned the chip for me. Actually a pair of chips. One to optimize performance, and one to optimize emissions. Of course I only use the "performance" chip at the track.
He kept and drove the car for a couple of weeks. It was a brand new engine, so he actually did me a favor and broke it in for me. IIRC, he logs the parameters while driving (uses Diacomm, I believe), then burns the chip based on those results. He also tests for "seat of the pants" performance and listens for spark knock, etc. He keeps burning chips until he's satisfied with the results.
The cool thing about it is that once he's done, it's optimized for *your* particular combination. He also said that he's never seen two 3.4s that used the same calibrations, or that ran the same. Probably due to the different "stuff" each of us uses to get our project running.
If you can do without your car for a week or two, it's the way to go.
Before you start tuning the chip, go ahead and get a new fuel filter and a new AC/Delco MAP sensor. I had my 3.4 tuned pretty well and finally noticed that the car had an old fuel filter on it. After changing the filter, all the fuel tables were off by a lot. Then, while tuning the sliding door sports car, I had the tables close but could not get a high rpm/load stumble out of it. Swapping to a replacement MAP sensor helped, but after a few days, the tables were off again because the generic sensor was not giving a consistant reading. It took a new Delco sensor to finally get the fueling locked in and so far (knocking on the artificial wood desk surface)I have not had to touch the tables.

I did mine with http://westers_garage.eidnet.org/scprice.htm . Great service and fast response but expect to mail back and forth at least couple times. Dyno time will help too to provide feedback. If you don't have a local tuner that's the only $$ way. Good luck

Question: Why did you have to send the chip back and forth a couple of times?? Did it not run right or what?

No matter who does the chip, to get it right "the first time" would require you to drive the car there and have in on their dyno. Otherwise, you start with programming based on a "best guess", which is refined further as you "test drive" with the chip.

How does one know if the chip is done right? How do I know if the vehicle is really performing to the best of its capabilities? I don't have access to a dyno.
