Default Tuning shops in chicago for LT1’s

Does anyone here know any shops that work on LT1’s in the chicago land area ?? Speedinc and a couple known ones don’t work on LT1’s.

Im trying to get pacesetter long tube headers
installed and at a later date this cam
https://www.summitracing.com/parts/cca-07-503-8

I really want to make this car a bit faster but most importantly I want it to sound more aggressive. I just don’t know who to go to in my area that knows these cars.

94 Firebird transam V8, 64k miles. Stock aside from Magnaflow CBE, Strano’s rear and front sway bars and a petris optispark.

Beautiful car! I too feel your pain on the lack of tuning options available for the LT1. That's why I'm seriously considering a 24X conversion. Superior driveability, tuneability, and power. Coil on plug is the real deal.

Solomon tuned my car with just bolt-ons and headers and I was impressed with how well it ran. If all your doing is headers right now reach out to him. He can also do full remote tuning for anything more - http://www.lt1pcmtuning.com/service/#Cable. If I stay with the opti this is the route I'm going, however I'm in the process of a full build on mine and considering a 24x conversion also.

Question as I’m kind of a noob. So I read over this 24x conversion kit you guys mentioned that deletes the optispark, so no more worries and apparently it makes the car run better and changes to obd 2 which is an advantage in that you can get the car tuned at many tuning shops !
Can I still get the long tube headers done first if I want this conversion kit? Or should I do the conversion kit First and then the headers and cam etc ? Does it matter what order to do it in ?

Take it to a exhaust shop. They will install the headers for you. Here is STL i've been quoted anywhere from $650 to $800 bux for install.

Don't do this unless you don't want to learn about your car. Plenty of how to's and installing headers is really not all that difficult. Just remember the air box on the passenger side is very brittle now because of its age and thousands of heat cycles. So if you get a header caught up in that it may crack/break. Nothing a little fiberglass/resin won't take care of. If you take it to a shop chances are they don't know/don't care about this and will jam a header and break that **** to pieces. Always do your own modifications if you have the means.

First, have a plan, know your budget, and understand all that is necessary to do the conversion for your car. Is your opti working fine? Has it been replaced? Do you have the money to drop on a 24x conversion now? It's not cheap, and you still have to pay to get your car tuned, though finding a local tuner will be much easier when switching to the LS PCM. So the question comes down to what is your budget now. If you are on a limited budget, just do the headers and get a mail tune (like Solomon or someone else you find). You'll be happy with the results and can then plan out what to do in the future.

I’m taking it slowly but my budget is whatever it has to be to get this car a bit faster and get it to sound more aggressive but not destroy an Important component in the engine/tranny.

My opti was replaced last year with the ventilated Petris one and I haven’t had any issues. Granted I drive the car only in summers a couple times a week so I’ve only put about 2k miles.

So my plan is Pacesetter LTH and this cam https://www.summitracing.com/parts/cca-07-503-8

Then that 24x conversion is very tempting.

Finally a pro charger.

Is there a particular order I should go about it ?
Is there a need for any of this or just some of those things ?

This is something I would do with time not all of a sudden.

You are leaving out some important components that must be done with a cam swap. I won't comment on the procharger. If you aren't tearing it down, my opinion is to leave the working opti in place until you get to a point where you're tearing it down anyway, or it breaks. My opinion, read up on everything and get a solid plan together based on your goals and what you can spend, do all the supporting mods first before thinking about a cam swap.

Hey guys so I was asking for quotes and I found this shop that has experience working on f bodies. They quoted me for a longtube header install $1400 with me providing the headers.

I asked for a cam install quote with valve springs (I’m providing the items) and they told me $2600 with a tune.

idk but I feel like that’s a lot. Or is it reasonable ? I’ve read some forums here but they’re all outdated from years ago.

Those quotes aren't unreasonable unless you already have the time, place and tools to do it yourself.
