This time last year my turbos blew at 120k miles and I bit the bullet and went for k04s. I tried to be somewhat responsible with my finances and went stage 3- for a year, a very long year but worth the wait. In hindsight I should have done everything last year and put it on my credit card. The car had more pep, but was unrefined and just didn't feel right. Hesitation, lag, uneven power. Now that is all behind me thanks to JH Motorsports in Lathrop, CA. They installed the fueling kit and did a custom tune for me. The car wasn't quite done around dinner time when I walked back to the shop so one of the guys drove me to get something to eat, it was a small gesture but that is what defines great customer service! They also fixed a notchy reverse gear free of charge for the delay.

They installed a manual boost controller under the dash, set to 21psi stock but adjustable as high as 30psi I am told. I dialed it up to 25psi for the ride home and was extremely pleased. Holy **** this car is fun to drive on the highway. I had to get off at a few random exits to accelerate back onto the highway again . The power delivery is maintained through gear shifts, as the tune holds the throttle for a split second when the gas pedal is lifted. 1st gear hits redline VERY easily, 2nd doesn't last much longer. I got home and took my wife for a spin around the block expecting her to impress her with the speed, although she drives the car daily and can row the 6spd quite well, she was more excited about the reverse gear being fixed!

With our first baby on the way, I'm selling my motorcycle and buying my wife an Imola B8 S4 s-tronic, easy to put in reverse and I get to have "Papa Smurf" replace the bike as my daily driver. Looking forward to the commute and a nice looking garage!

I love my S4.

This is about where K04's would be on their compressor map at 25 psi.

The data I'm plotting is from the F4H that I now have and this is where that 25 psi plots out on the F4H map. The boost is around 24.5 psi at the uppermost end.
