ok here it goes.
i have a 2003 pt gt with a stage one pcm, custom dual exhaust, bov, and cold air intake. When i first put in my stage one pcm everthing worked excellent way more power ect. but I have had it in for around 4 months and suddenly when i step on the gas hard it bogs down big time. I tried changing spark plugs and wires but it did not help (iruduim gapped at .32 ) no error codes are showing up I am baffled. So i took it in to my chrysler dealership they looked at it and after charging me an hours labour $100.00 they told me to take my stage one out and put my old computer back in rrrrrrrrrrrrrrrrrr . anyway i am going to try that and see if it fixes the problem but I really really do not want to . Does :anyone have any suggestions.... i am deperate !!!! thanks to all who respond.....
