Put new injectors and now an SES? I put 30lbs, ls6 intake, and had it semi-tuned about a week ago and today while I was cruising on the hwy, a code PO121 (TPS/pedal position sensor A CKT Range/Perf.) came up, what is this and why did it come up? What will need to be fixed? Thanks.

I don't know the details, I just know my buddy changed some things with hp tuners so I could safely run the injectors, the car will be dyno-tuned in about a month. He also said that before he made the changes, hp tuners said I was 99% were I should be. (i would guess fueling). The car was tuned a to 12.9/1 AF before ls6 intake and 30lbers. So what's happening?

all you need to change with the injector install is the IFR- injector flow rate, it is online here and if you want i can email it to you and you can go to your buddy again and tell him these are the numbers that need to be put in it.
unless you have done a LOT of mods you won't max out your stock injectors, at least not at 99%.
this could be the wrong answer....but whatever he changed he needs to change it back and just change the IFR table which is table B4001
