It is the hottest summer on record for Central Texas and i get some hiccups through the RPM's when I get on it a bit, it does not seem to do it as much when it is cooler outside.
What is your take on this?
What is the optimum temperature to get a the best performance out of the car?

 

Turbo cars dont like the heat at extreme levels your seeing, I bet your just seeing the car pull back a bit. I believe you could run better gas (higher octane race type) and see if that helps.

The cooler denser air is the best.

 

is 82 degrees too hot? what would be really good?
what Octane would you run? 98, 100 or 103?

 

82, no, I was thinking your talking about 100+
82 should be A ok even with your mods. Who tuned your car?

 

it has a Softronic tune. I am trying to figure out how to fix the issue with them.

 

You have Dan's upgraded VTG package right?

What do you mean by hiccup?

 

It is like a surge... the turbos are spooling fast, the car is trying to digest the power, it pushes it back then it takes it in and it is happening fast, it feels like a hiccup or a freeze then as if you are getting pushed back in your seat when the power is in again...this was explained to me by an expert trying to help me communicate this to Softronic as i am not a mechanic... we need some more data log to go forward but I may have a solution soon...

 

My car isn't as "aggressive" in the heat but nothing like what you are saying...and by heat I mean excess of 90 degrees.

 

It gets worse with heat but it did the same thing at about 82 degrees a few days ago

 

Did you replace the BRV's?

 

and that part os? sorry

They say its a must do when your running higher boost vs. stock

 

Dan sent me a set, i have not had the time to install it as i normally go to the local dealer for this, is it easy and do you recommend installing it myself?

 

Do you have a durametric interface to log data?

 

I got a lot of logged data about 8 files or so. I do not have the cable on me now...
