P0175/0172 Codes???
Hi, Its been a few weeks now since I installed everything to complete my powerdyne supercharger setup, but today I got a service engine soon light. I scanned it with my xcal2 and got the codes p0175 and p0172 which from my research are bank 1 and 2 rich. I have installed new bosch oxygen sensors, new 90mm Maf, new 42# injectors, and a custom sct tune by Mike. Could it be the tune thats causing these codes? I'm planning on calling Mike on Monday to see what he thinks, but any helpful information is appreciated. Thanks.

As is pointed out in the documentation you got with our tuning, you need to datalog the vehicle so that we can review that data and see if we need to dial in the A/F's - which is most likely what needs to be done, assuming there are no mechanical issues.
Remember, this is *custom* tuning on a highly modified & supercharged vehicle - so you need to do your part and get us the data as per the datalogging instructions you received with your CPW's before you got the tune, and as is pointed out again in the additional documentation that came with your tuning.
So do the datalogging, including having the A/F's tested as per our docs, and get that data to us so that we can make any adjustments that are necessary - this is very straightforward and standard procedure. That's why we write all of that documentation, so that everyone will know *exactly* what to do.
If you have any questions, call us at the number listed in your documentation, OK?
Thanks, & talk to you soon!

Just got home from the dyno, doing the rest of the datalogging now. The dyno guy said it was running way rich and said there is room for improvement. Max hp. 256.37 and torque was 313.09. I'll get all the datalog info to you asap. Thanks.

After reading through the datalogging instructions again, I realized I was susposed to do the load datalogging with the xcal2 while on the dyno. You are susposed to do both at the same time. Can you still datalog after the fact, or will the results be inaccurate? I'm trying to avoid another $75 dyno fee.
