PRICE:
APR Stage I - $1299 plus tax and install (typical install ranges from free to $99)
Chipwerke - $349 includes tax and free shipping
INSTALLATION:
APR
The APR programming was installed at USP Motorsport. Install time was approximately 45 minutes. All installation was conducted with flashing through the OBDII port. Re-installation of stock OEM software was also conducted through the OBDII port. I was advised that APR automatically flashes the exact version of the OEM software that was on your car and also resets the flash counter. Although there is no guaranteed way of avoiding TD1 concerns, it appears that by doing both of these things people are currently avoiding TD1 flags. It is important to note that not all tuners reset the flash counter and not all will make sure your software versions match. This was important to me.
Chipwerke
Too easy. You connect the two pairs of intercept cables to the two G31/G72 MAP/IAT sensors. You are provided several zip ties to route the wires out of the way. No tools are needed. Installation time was 10 minutes being careful. Removal is the reverse of installation. Obviously this method of performance increase was desirable to me with respect to avoiding TD1 hassles. This module does not change the factory ECU settings in any way. It changes the interpretation of the outputs but does not change the code. There is no TD1 detectability.
CONDITIONS OF TRACK TESTING:
Stock testing was performed at Palm Beach International Raceway on March 25, 2015. Temperatures were approximately 78 degrees. All three runs were within .06 hundredths of a second of each other and within .3 tenths of a mile per hour of each other in trap speeds. Consistency was obtained. No external factors appeared to skew results. Vehicle was run in dynamic mode with ESP/ASR off. Factory Launch control was utilized. 93 octane pump fuel was utilized.
APR Stage 1 testing was performed at Palm Beach International Raceway on March 18, 2015. Temperatures were approximately 76 degrees. All three runs were within .1 tenth of a second of each other and within .6 tenths of a mile per hour of each other in trap speeds. Consistency was obtained. No external factors appeared to skew results. Vehicle was run in dynamic mode with ESP/ASR off. Factory Launch control was utilized. 93 octane pump fuel was utilized.
Chipwerke piggy back testing was performed at Palm Beach International Raceway on April 8, 2015. Temperatures were approximately 80 degrees. All three runs were within .2 tenth of a second of each other and within one mile per hour of each other in trap speeds. Consistency was obtained. No external factors appeared to skew results.Vehicle was run in dynamic mode with ESP/ASR off. Factory Launch control was utilized. 93 octane pump fuel was utilized.

DRIVING IMPRESSIONS:
APR
The power deliver with the APR software was extremely linear and as smooth as stock. There was no jerkiness. There were no problems with part throttle behavior. There were no misfires. There were no CELs. The power difference was mildly to moderately evident. The programming gave increased confidence when attempting passing.
Chipwerke
The power delivery with the Chipwerke piggy back is immediately noticeable. There is no definite jerkiness, misfires or CEL but the car does appear more sensitive to part throttle inputs. When my wife drove the car she says to me, “What did you do to it? I got afraid I was going to rear end somebody when I push on the gas.” There does appear to be more power everywhere in the rev band. Important to note again, there has been zero significant drivability issues. There is no “cutting” or jerkiness. There are no misfires detected. There are no CELs.
