Impressive!!

 

No doubt! it's worth it.
BTW nice pooch is that an Australian Heeler?

 

 

 

super impressive! the 60ft is nuts on the stock Pirellis!

 

it runs very good , crazy 60' . what aftermarket exhaust does it have ? cats or race exhaust without cats ?

 

Awesome results! Thanks for always trusting us with your cars! It's great to see such an easy (and minor) upgrade produce such strong results.

Excited for the next stage

 

So this is ONLY a tune with no exhaust or intake changes?

 

I know for certain it has stock Y pipe, stock plenum, stock Intercoolers, stock exhaust manifolds, stock turbos and stock tires. Not sure if has stock cat back or Tubi catted street system. Before and after runs made with same exhaust, whether stock or Tubi cat back. Power (.5 and 6 mph) is in the tune. On my 991.1 TT, cat back exhaust alone made no difference in 1/4 mile times.

 

exhaust will make a difference if it's tuned. nothing drastic, but some.

 

Agree, including the difference of losing power with some exhaust systems.

I’ve seen close to zero gain on a stock 991 TT with a cat back only other than an improvement in sound. The stock exhaust is pretty good for stock or 93 octane tune power levels. When you go to larger turbos, exhaust more critical.

 

This car has only our GIAC Stage 1 tune and Tubi Race exhaust.

 

Hey Tom why doesn’t this have the stage two tune if it has the exhaust thanks Mike

 

What's up Steve, Glad to see you're back in it. Have not spoken to you in a minute (good old friend from the CL65 days )
