Wanted to know if anyone has done any peformance mods with their E300 beyond speedtuner chip like:

- Boost control valve that would allow the turbo to give a few extra PSI to control smoke after IP give more fuel.

- Cut out cat, would allow for faster spool up and worth a couple of more PSI without ECU or boost mods.

- Bigger intercooler, control intake temps; cooler air = less unburnt fuel.

- K&N filter and filter pod, more air in the turbo intake = mo better.

- Bigger injectors, more fuel along with more air thats been cooled = !

I own a 97 TDI Pasat, these mods along with ECU tunning on the TDI's 1.9 liter engine would give the TDIs 250 ft/pds of torque on a dyno (about 277 to the crank) reliably and make for decent stop light racer while keeping the MPGs in the earlier to mid 40s.

I figure with the W210s 3 liter engine that's as smooth as the one I've test driving I'd be able to knock the socks of of 250 ft/pds to the ground and keep around 35 mpgs or better too.

Thanx much
