Recently purchased an Alta Access Port and I'm curious how I would be able to tell if you have a tune installed already. Reason I ask is because my MCS feels extremely fast already and has no issue getting to +100MPH already. I've been watching the scan gauge and I've seen 13.8 boost on occasion. When I get the alta access port will it tell me if I already have a tune. I don't want to overwrite if I have something already.

Any ideas?

 

14 psi is what the stock mcs hits in overboost. Doesn't sound like you have a tune to me.

 

OK, just wanted to be sure. Thx Creeve

 

ya i agree with creeve, i see 13.8 on my scan gauge. also check timing and afr on your scan gauge. that will tell you if your tuned

 

I can't think of a car sold in the US today that has an issue with hitting 100+ MPH. My Justa is certainly capable of it!

 

I agree with you, it was more around the time that it takes to get there. There are current cars on the road today that I would not take over 100mph, and they aren't much more than a few years old. Mainly American built cars.
