Dyno Tuning

[slo-joe55]

Hey Guys,

I am trying to get a good idea of a approx. cost to have my GN tuned on a dyno. Talk to a local mechanic he said cost could be anywhere from 500.00 to 1000.00. Which would include the dyno time and tuner. Does this cost seem to be in the ball park? And after the completion of this tune what kind of info should I be left with?

Why are you wanting this done?

Stock computer car or aftermarket computer car?

Engine stock? Modified? Heavily modified?

Engine is a custom built 3.8 originally built for comp, however the car will now be drivin on the street. Computor system is a fast system. Spent $$$ on this built starting with a Hi-nickel block. Figuring this would be the best way.

If it has a FAST, then it needs to be tuned. Use a Buick tuner as they know the quirks. Yes on the 500-1000 figure.

All factory blocks are high nickel.

This is where you put a post "Looking for tuner"

If your not going to race the car, you may consider putting a stock computer and chip back in. As it requires virtually no tuning at all.

The car will make some trips to the track with are local GN club members. Didn't know that all GN blocks were hi-nickel. Was told on this forum that nickel blocks were not the standard when these car were originally built, the built sheet made it seem as if it was something extra. (Thanks) The car has been gone through suspension, trans and engine the one reason the aftermarket FAST system was put in place was to handle the 83# inj.

Somebody at somepoint had to convince you to go this route.

If the car does not have a roll bar/cage.. its limited to 11.50 as any faster you get the boot. 11.50 can easily be done on 60 lb injectors that can idle like a cadillac and not require using an aftermarket computer which you'll be married to a tuner.

I guess my point is careful what you ask for... keeping things simple always yields the best results. Its not a money thing.. its an issue thing. For a car that goes to the track a few times a year.. no way would I build it like this for a customer. Unless I wanted a marriage.

My race car has a FAST. I love it. But I also understand its not for everyone.

IF your car has a roll cage.. IF you plan on running 9's in the 1/4 at very high boost levels and dont care that it "blows up".. IF you can live with a laptop in the car pretty much all the time for logging and tweaking the tuneup.. IF you have this scenario.. The FAST is for you.

If you dont want a laptop.. dont want to watch anything.. dont want to mess with the car.. dont care to learn to deal with it.. then.. you were sent the wrong direction and will burn more $$$ and grief than you'll want.

Just my humble .02

I get your point. Dont mind the laptop or the learning process. When my original motor blew I took the opputunity to have a nice motor built, originally when the motor was ordered it was aimed at competing in the TSM class in BG. However by the time the engine was completed the times in that class were just to fast. The goal changed to a solid mid 10sec street car and keeping the boost no more then 22lbs.
