I know it probably sounds dumb, but should I do the dyno pull in 3rd or 4th gear? I'm not sure which would make it "easier" to tune the car.

Any other advice you can give me would be great. I'm tuning for 20psi(for the track), and also 15psi for daily driving.

TIA! Here's crossing my fingers to not blowing it the eff up


thanks guys!

You'll want to do it in 4th gear. It has a closer to 1:1 gear ratio.

Personally I like 3rd gear pulls but my talon never got to a dyno. heh

EDIT: Try both and see what the difference is

I was always under the impression that 3rd gear was the way to go, but then again I've never been on a dyno so I'm just talking out my ass here.

thanks for the responses guys! I had to reschedule for next saturday because some guy had a group of ten cars that needed the dyno today and I guess 10 dyno $$ is better than 1. Oh well, they are giving me my 1st three pulls free for the inconvenience! I'll post the results up next saturday. Merry Christmas.

Devin, our 420a's should be dyno'ed in 3rd gear. If you have any questions you can call Aarron over at Victor Research in East Hartford, Ct. 860-282-RACE. He's the owner and does the dyno work over there. They are a mitsubishi "speed shop"

Interesting. I did the dyno pull on my bike in 3rd gear, but I'm geared quite a bit. Someone recommended I try it again in 4th, but I didn't have time. I'm hoping to get a full tune soon, so I'll try a 3rd vs 4th pull on the bike and see if it does the same as what you found.

The gear ratio for 4th gear is 1.03 and 3rd is 1.36 (or something like that). Refer to the factor service manual or the main site for the exacts specs.

In 4th gear your motor and the output shaft are spinning at almost the same speed. In 3rd the motor is going faster than the tires.

Don't know the gearing in a 4g. Their 3rd may be closer to a 1:1 gear ratio than ours in 3rd gear. But for the 420a with a stock 3.94 geared trans you should be dyno'ing in 4th gear.

My .02 cents. But dyno'ing isn't an exact science anyway.

Yep. Mainly for tuning and for getting a rough idea of how mods improve the car. The numbers are good for a sig too.

So, does any of that help you Devin, lol? I'm guessing you'll have to discuss that with the particular tuner.

And I concur 100%, it is a tuning device used for comparison of changes that you make.

Whats it cost to dyno a car say 10 runs

We will build you bigger and stronger


Wake up and drive my ass... More like wake up and fix it.

If the opposite of Pro is Con
then the opposite of Progress is Congress

It depends on a lot. For my last 4 runs I did it cost me $70 and change. The first three were like $60 then I got charged for the last one (he did me no favors. Geez, I'm doing all the tuning and it was less than an hour but he still hit me up....anyway). Some places will do it by the hour, some places will give you like the first 3 for one fee then charge you for time or pulls. If you are tuning it, will be one price, if you are having them tune it will be different.

Lots of different variables. If I was to do 10 pulls, with them tuning, it would probably cost me (at this dyno) $150 for the tuner, $100 for the first 3 pulls then another......Wait, let me just shoot you an addy and you can take a look at their rates. just click on the dyno links.

That'll give you an idea.
