Willall Racing Stage I tuned CLA45 AMG M133 goes firstname.lastname@example.org in the 1/4 mile
Nice results here from a Stage I tune only CLA45 AMG running the Willall Racing piggyback tune. These numbers essentially back up in the CLA45 AMG what Wilall Racing already hit in the A45 AMG (not sold in the United States) which was a 12.280 @ 112.14
. Utilizing the same Stage I piggyback tune on the CLA45 AMG yielded a 12.381 @ 112.82 1/4 mile run. It's safe to say the established performance level M133 engine owners can expect from a Stage I tune is low 12's in the 1/4 mile at around the 112 mark.
It looks like on the stock turbo with supporting bolt on modifications such as to the exhaust or intercooler 1/4 mile ET's breaking into the 11 second range are possible. With more aggressive Stage II race gas tunes maybe even mid 11's are well within the realm of expectation.
Pretty impressive from a factory 2.0 liter four-cylinder and likely a more stout platform than most likely anticipated.
