Every computer controlled third gen needs custom tuning!

[JSPERFORMANCE]

After about 10 years of driving my formula with the stock 305 chip in it I had gotten used to the quirks of the stock tuning controlling a modified 355. The car would idle high because of the increased air flow registering, it would run rich as hell, gas mileage sucked and it wouldnt pull as hard has I thought it should have. One other thing I kind of liked but wasnt good was the three foot flames it would throw when I mashed the gas.

Well with the help of my new expert tuning team, Kevin and Dan my car feels like a whole new beast! It idles smooth and at the right rpm, pulls to 5800, dosent knock, dosent smell rich, and unfortunately the flames are all but gone..

First I want to thank these guys for putting their work into getting the tuning process together.

Second I would suggest everyone gets their car tuned even if you only have small mods or are almost stock. The computer can be made to do all kinds of stuff like; running the fans cooler, making the speed limiter go away, adjusting for increased engine noise due to a aftermarket cam, making the shift light come on when you want it, adjusting for bigger injectors, and almost endless other possibilties.

If anyone else is interested in getting their car tuned right by the professionals at JS Performance we can set up a "tuning day in the near future and get all these cars running how they should be..

[TheBandit]

if you will tune my lt1 i will start saving money right now, and garentee you id come down for a tune. like you said, my car runs rich, doesnt pull as hard as i think it should, doesnt run right at all, :/ but its a 94 so i dont know if you guys would tune it

[Fast92RS]

I may require some help in the future. Its good to know you are doing tuning on third gens. I will keep you in mind once I get my car running.

Yeah I'm serious. I'd like my truck to run good when its cold. It runs like crap on the stock fuel tables then it warms up and switches to run off the o2 and runs great.

If you are beating on your truck when it is cold the last thing you need to worry about is the tune. Warm up is a good thing..

you should do mine :D

[Kat]

you should do mine :D

:) A buddy of mine has a 95 Z that I'll use to beat on. If not the ex Dumb effin gf has a 91 Z Vert with a LT1 in it that I'll use :)

[JSPERFORMANCE]

In other words, we are still working the bugs out if the lt1 tuning and getting pricing together for everyting.

If anyone is interested, post or pm me and I will add you to the "waiting list" and once we get things all ironed out you will be notified..

Use mine as the guinnea pig. :) What program are you using for it?

[Kat]

For the 86-89 MAF 90-93 SD cars I have TunerproRT and TunercatRT. For the LT1 stuff TunercatRT and Datamaster.

[Ian]

would you be able to tune OBD II LT1's?

[Kat]

Not yet :)

[Untamed]

Ok I'm a little lost. I see the posting about the LT1's, but someone above mentioned TBI's. Can an L03 be tuned?

[Kat]

Ive never messed with TBI honestly. Well atleast the puter side of things. Im sure that I can learn in a few hours :)\

I did have a 90 RS that got totaled right before I got into the prom burning stuff

I 85% of the time do. Its just in situations like when I'm running late to school/work. Or need to split fast its embarassing to stall the truck because I need to leave in a hurry.

[JSPERFORMANCE]

you probably have other issues if it is stalling

[JerzLT1]

if you can tune OBDII LT1s and can price around MadZ28 id gladly go to you instead

[Tru2Chevy]

I'm pretty sure that he's said before that it's cammed, not sure what other mods. But stuff like that on a stock tune could be causing it.

Depends on the cam. In my old iroc I had a LT1 cam and it ran ok on the stock tune. In the vert with a XR282, it wont even idle at all on the stock tune. :D

[DaSkinnyGuy]

I just need to replace my passenger side header first but I know my car could use a tune with the couple of mods I have.

[DaSkinnyGuy]

Are you able to tune a 92 Bird 3.1L V6 Auto.
