Message Well I always thought the car ran strong. I installed a VDO 0-15 boost gauge and to my surprise, it ran right up to 14 lbs. and held steady! No spike, but a very quick spool up which I attribute to the GD super splits and test pipes. (no cats in the exhaust) The ECU shows no signs of upgrade except a marker note 'group481'.

BEFORE everyone goes nuts about running lean and burning pistons please note I have already driven this setup for six (6) years, and 10,000 miles. I don't beat on my equipment, and the car has never been tracked, dragged or run at extended high speeds by myself.

I guess I'll have to start looking for some boost jets somewhere in the wastegate lines. Is it easier to do this from underneath? Are there any other logical explanations for 14 lbs boost with a thought-to-be Stg II setup?? gordo
