Previously I had a 2013 335XI M Sport. Car was only running BMS Intake, BMS Intercooler, VRSF charge pipe and BM3 Stage 1 tune.
Car was an absolute monster. Based on the in car gauges, I estimated around 400hp and 450-475tq. Throttle response was instant and it pulled like mad under full throttle.
Current car is a 2016 M235i Xdrive. This car now has CTS Intake, CTS Chargepipe, Gplus Intercooler, VRSF Catless Downpipe and BM3 Stage 2 tune.
This car that weighs ~200 pounds less, with the addition of the catless downpipe and more aggressive tune file, feels slower and based one the in car guages ( I know they are not exact) is not really making any more power. Maybe a little more HP and the same TQ as the other car.
I am very confused by these results because the addition of a catless downpipe and matching tune is advertised to be a massive power gain.
Also this car is the EWG turbo vs the previous PWG turbo, which is also advertised as having more top end power when tuned.
Any thoughts, or tuning points I missed when designing this build? Don't get me wrong the m235i is fast, but absolutely no faster than the 335i that had less modifications.
**Side note I love the sound of the VRSF Catless Downpipe. It makes the car sound like a high performance vehicle and really is not over the top unless you are WOT. Even my GF likes the sound, and doesn't complain.
I have to say I am shocked at how bad it smells, after some 0-60 sprints you WILL smell the lack of a catalytic converter with your windows down or after you park the car and get out. Hard to say its worth it because right now it doesn't seem to have added much power or throttle response over my last car that didn't have this upgrade.
