I'm trying to decide whether I should have the MTH header and software installed on my '04 MCS (dealer installed JCW tuning package), I've read most of the related threads, but need assurances from those who already have these modifications.

I am specifically concerned about the performance claims (240HP) and the tractability of the car for street use (hypersensitive throttle) after the upgrade.

Does anyone know if MTH does Christmas specials (discounts)?

My only other modification has been the addition of a 19mm rear sway bar which was a tremendous improvement to the understeer problem.

Please give my your opinion on the MTH header and software as soon as possible.

ps - does anyone know what the torque metric is after the install?

 

MTH does not make the throttle response hypersensitive -- rather the drivability is improved.
There will be no Christmas discounts on MTH products; the prices are actually going up at the start of 2007.

This thread should be relocated to the MTH Forum and not in the General Interest Forum.
