I have an 05 E55 with long tube Kleemann headers, Kleemann tune, and 168mm crank pulley. The primary cats , secondary cats and resonator have all Ben deleted, I added an x pipe the exhaust finishes through stock E55 mufflers. I am currently adding a 82mm throttle body and 83mm supercharger pulley and belt wrap. Is anyone out there running a wide band with these mods and a Kleemann tune ? I need to know what fuel/air numbers you guys are seeing . My buddy has the same set up but with a eurocharged tune. I know what his numbers are but don't know how similar the Kleemann tune is to the eurocharged tune. I could really use this data to help me know where I at and if I'm too close to a lean reading to the next steps I'm thinking of taking without running shy on fuel. As I said , my buddies car which is identical except his tune is eurocharged should handle it based on his wide band numbers. I just need to know if his tune is similar to my Kleemann tune based off of the wide band numbers from a Kleemann tuned car. Sorry this was lengthy but if anyone is equipped to provide these numbers for me I would GREATLY appreciate it. Thanks everyone .

Honestly I would get your own Wideband and see ,to many variables , it's way cheaper then fixing a popped motor.

if you can get a wide band like zeitronix or something to log the air fuel that would be great. Keep in mind especially since you have a pulley that air fuel needs to drop as soon as you floor it. I seen a lot of tunes lean up till 4,000rpm then it richens up. 11.5 to 11.8 on a strong tune, is good to shoot for.

I'm considering on getting one but I'm going to dyno the car in the next. Week or two so I'll be getting the numbers then anyway and I'll be putting it back on the dyno if or when I make any more mods to see what I gained so I m debating weather or not to get one .i ready don't NEED one based on that but may put one in anyway.

Any modded car should be monitoring
Afrs
Timing
Iats
Boost

Those 4 are very important
Zeitronix with dashdaq gives those options and more

i have a aem wideband with OEtune and i see 10.8 to 11.5 afr at WOT... depending on the outside temp

Your flying blind ,it's cheap insurance ,my fuel pump started going bad ,never knew it at the time ,but all of a sudden I saw 14 AFR on A run
If I didn't have those gauges kapow for sure

Yeah, I was initially thinking because this car is so mild compared to my past modded cars that I may not do it but the Zeltronics set up is priced well considering what you get . It's worth throwing that into the mix just for the insurance and piece of mind .

About 800$ for zt2 and dashdaq. If you go for boost sensor then add another 60$
