DP Tuner / Boost ?
I have a DP tuned 2001 7.3 and i noticed the other day that my max boost is only about 22-24. I am pretty sure that when i first put the chip (2 yrs ago) in i was getting at least 28 or so. But, a couple months ago the ford dealer replaced the turbo pedestal, one injector, and a few other things and i haven't really got on it much till the other day when i noticed this. Is this normal, or should i be checking into something.
Also, lately my lock-up has started kicking in and out when under light throttle, mainly on the 80 econ setting. I believe it is probably from my tuner being set for 3.73's and i have since changed to 4.56's. But i intially didn't have the problem, and it has since became more regular. It doesn't seem to do it when set to the stock postion, and less when on the 100hp and up settings.
Thanks for you time and i look forward to any information.
