Going to the dyno thur need some help!!

[JDR7919]

I just found out that my brother is taking me to have my car dynoed for Christmas. The shop is very familiar with dsmlink which I just got. I have been having problems getting it set up. I just wanted to know what I need to do before going? I found I have a boost leak coming from the shaft seal in the tb. Do I need to make sure that is fixed before going in? How hard is that to fix?
I was going to change the spark plugs and wires, bring another boost controller and a extra set of plugs. Is there anything else I should know?

Thanks

Deffinitly fix your boost leaks, changing the plugs and wires is also a good idea.

Just make sure you have the car in tip top shape.

Shaft seals leak won't change the dyno reading too much, make sure everything is tight, no leaks and check your IC pipes. Weak things usually will surface on a dyno..

Swap out your t-body shaft seals, and use a bit of hylomar, or copper spray to be sure of a good problem free seal. Make sure not to over tighten the bolts as it is just aluminum and if you strip them, it will cause a larger leak then you have now.

If you change plugs, make sure they are NGK BPR7ES's gapped to .028. Make sure your wires are in good shape, or replace them if they are old. I wouldn't think you need an extra boost controller but it's up to you on that one.

Try to get as best a tune on your car as possible. Run race gas if you can. You have DSMLink, w/ race gas you can bump up timing and take out more fuel than with regular gas, while reducing knock. Thus resulting in more power.

I have been having problems getting dsmlink tuned. I keep getting stutter at 4000rpms. If I pull alot of fuel it goes away. I think Im running rich from the boost leak.
