10SECS4 Tune, anyone tried it?

[ttboost]

Yep..I tried a 20psi file for a while...but too much heat too much retard...back to a 1bar file...

[10SecS4]

What were ambient temps when you tried 20psi? Was it on the dyno or on the street?

Why would you ask when you know 20, or even 18psi is pointless with these small turbos?

[10SecS4]

I disagree. While it may be pointless on pump gas with the stock wastegate actuators in the dead of summer, it could be a different story with colder temps, higher octane and aftermarket actuators (like ttboost is running).

I would still think it would over spin the turbos, but I see your point under ideal conditions. Certainly not DD conditions though...

RS6 turbos have a history of running at 20+ psi levels for many miles over the past 5-7 years on B5's (with power gains seen in the 20's). They're definitely out of the high efficiency zones at those boost levels, but you're not necessarily reaching an absolute ceiling at 18 or 20 psi.

I was running 20lbs in 65deg weather on pump...doesn't like it...on the dyno it wasn't bad, on the street, another story...plus heat soak with stock IC's. It did exactly what I thought it would do. It feels almost as fast at 15 -16lbs with no timing retard...

I think they tend to spool up quicker, overboost easier and make more heat on the V8....

Wondering if anyone knows about whether my 10SECS4 tune will keep the code from popping up if I gut both sets of cats?

Thanks!

I have gutted downpipes, but the lower cats are still in place so can't comment specifically if you remove both points of emmission control whether or not a code with throw. I have no codes with the precats removed.

Just ask Marc. I would doubt they (rear O2 sensors) are coded out, but sure it could be done with a re flash.

So you don't have emissions testing I take it?

Well Florida does not have emission testing, but this if for track purposes only! I would never do this for a street car!!

I would ask Marc, but his inbox is full and I cant message him.

You only drive this car on the track?

If I do this, then yes sure track car only, right that's it.

He needs to clear his inbox!

LOL... someone is a little slow

The point is having gutted DP's has nothing to do with driving on a track, or street for that matter. Emissions is the only worry, and if it's not around you're fine! You could also get the tune updated for lack of back pressure from the cats, should be good for 15-20hp more.

[Bigglezworth]

Being as I am afforded the opportunity to drive two cars with the same tune - one with the gutted DP's and the other without - I confirm gutting the DP's is definately noticeable.
