What are the best brands and type for GN if improving top end speed is the goal? Appreciate the help.

Add Al's Cafe Craig you need to add Al's on Wednesdays to your list... Weather on Wednesdays always sunny for the GN's. Get your car ready to drag on Thursdays at PRP!

Ready for the Season Craig, Sorry, I missed your Merry Christmas greeting and the meeting last night my brother had for the South Park cruise. I PM Jason about looking at some early Spring work on my car. Injectors and a new chip. I also am looking for lightweight wheels to switch my slicks...

I want to switch my wheels when I drag to a lightweight wheel and switch back to stock wheel on regular tires when I don't drag. Any suggestions on a light weight wheel type and where to look?

Hey Jason, I think me and my brother are ready to look into a few things. For me; 1. new injectors 60lb 2. new chip to replace my thumbwheel chip 3. I want to buy some light and hopefully cheap wheels. I will switch with slicks to drag, but want reular tires on good wheels. Any idead...

Have a great Holiday season to you and your family. Thanks for all your help on The GN and my brothers TTA. We appreciate it! Vince

Rev em Up Cruise Thanks for coming out guys. 550 cars and a good time, unfortunately a 20 minute rain towards the end. Lots of good comments on the event. The PRP this Thursday fell through, weather maybe iffy as well. We are looking at next Thursday, August 12. Jason, I wanted to get a day to...

I meet you at Caste about a month ago and then at Wexford, I am a new GN owner - Vince. My brother has a 89 TTA and is considering some work to be done. I gave him the card you gave me. His name is Jim. I have a question, I want to get new drag radials. I have BF Goodrich 235 60 R15, can I go to...

I have a 1987 Buick GN and I am thinking of buying a scanmaster. I thought I saw a scanmaster called 2.1 when I looked at the Full Throttle site a few weeks ago. Now I only see one scanmaster that states neither 2.0 or 2.1. Is there only one scanmaster now? How do you order a 2.1?

To install a new gauge...there are two sensors, the correct one is on the passenger side?

I just installed a new Caspers Knock Sensor Gauge that opperates by green-yellow-red lights indicators. The guage is suppose to work by alerting you if knock occurs by flashing lights. However, all lights are on/visible. Does anyone know why the lights would all be on? Maybe a ground wire problem?

Anybody got any experience or good websites to get Buick GN window stickers, build sheets etc. Anything that would have came with a 1987 Buick GN if you would have purchased it new.

While not the latest chip, I hear Caspers ultra chip works pretty well. I guess you found out, #0 is antitheft, #1 is parade mode and #2 is stock. My question is what changes need made to the car if you decide to go up to one of the higher levels...like 5-7? Boost, timing, fuel etc.

Lisa - when I get to the point of looking for the the Comm#, I do not see any. What is happening is its hard to go any further without using the Hardware Update Wizard. The Wizard is of no help as I have no disk. I tried to install manually without a disk, but to no avail. This really needs a...

Thanks for the help. I should be able to try this sometime this week. I appreciate the direction and will let you know.

I bought a 1987 GN and the owner gave me the Turbo Link Program which I downloaded to my laptop. The cable he also gave me goes into the cigarette lighter, then another to the larger computer port leading to the ECM and then the third to the computer. I bought a DB9 to USB converter so the cable...

Caspar Thumbwheel Chip. If you moved the chip from stock mode number to one number above stock level, do you still run gas/93 octane? What would be the chip level that you would consider/use gas different from 93 octane? ( chip has 7 settings ) What would the chip level be that you would...

All good stuff, I am a new owner in Pittsburgh as well. I am trying to get a handle on the scanmaster. As I mentioned, the prior owner has upgraded the car with many of the things within this thread. The prior owner gave me the computer program and all the tools to connect etc along with the...

I also bought a GN, in my case, over the holidays. I second that this site is awesome and the people are not only knowledgeable, but very friendly in conveying info. My 87 GN is not stock, but nicely upgraded by a car-loving and passionate former owner. Includes a fuel pump, fuel pump hot wire...

The " 3.8 liter turbocharger" script that gets placed on the hood ( engine rise ) on the GN lets say after a paint job....is there a measurment/dimensional way to put the script on the car? It looks like it is just centered on the length front to back on the rise and up and down. Just wondering...
