Hi - Thanks for all the feedback - Trap oxidizer has been removed - I'll check the odometer - just assumed it to be fairly accurate - Gets 20 - 21 on mixed freeway/city and I too use the turbo - have noticed the high rpm (actually a little annoying since I like to cruise around 70) about 3250 on the rpm - Car has excellent response when warm - turbo comes om much faster then others I've driven (85 fed and 83) I'm begging to think the Calif version won't be good for much over the twenty - I plan to set valves this weekend and find the vacuum leaks too - Does have the recommended tires ( 14s) - after hearing reports about the EGR and Bypass I was actually surprised the mileage didn't improve at all? Once again thanks for all the suggestions !!
