My Renntech Tuned E63 S beat my GIAC Stage 2 991 Turbo in 2 of 3 Roll Races
I brought both my cars, my 2015 Renntech full tuned and Renntech sport mufflers E63 S and my 2014 GIAC Stage 2 race gas tuned Europipe exhaust/IPD plenum 911 Turbo S using MS109 race gas) and raced them against each other in three straight races.
The E63 S beat the highly tuned Porsche 2 of 3 races. Seriously.
In the first race, when the cars were cool, my 911 killed my E63 S by many car lengths. But then heat soak set in on the Porsche. And my E63 S won the second and third races! I was driving the E63 S in all three races and my Goldrush rally teammate was driving my 991 Turbo S.
Here, at 3:20 you can see the E63 S beating my black 991 Turbo S
Here are the time slips. [EDIT: having an upload problem with that picture so will post later]
The E63 S was car 37 and the 991 TTS was car 38. The ETs and traps for the E63 S are correct. The ETs and first trap for the 991 TTS are correct but its second and third trap speeds are not correct (Slipstream has problems with its timing system at the meet).
My E63 S beat every BMW M car it faced and it faced many. One super heavy modded M5 with water/meth injection, catless downpipes, intake and tune pulled harder but he was DQed for a start speed of faster than 70 mph. My E63 S only has a tune and mufflers.

question, does your ECU tune have better throttle responds or lag on takeoff?Trending Topics

Bhp. 736 bhp if you drop the $5k for their intake.
With respect to the spark plugs if you get the tune you're supposed to change them between every 10,000 and 15,000 miles to prevent misfiring as the tune places them under greater load. I changed my first set at 9500 miles prophylactically before a roll race event but they had shown absolutely wear according to the dealer's AMG service tech and could have probably made it to 15k. As I recall Renntech found that upgraded spark plugs were not better than the OEM ones
