Time for a Tune - UpRev Price Check

hansoac

After installing Stillen CAI's, Full GTHAUS CBE, and Fast Intention Long-Tube Headers, I understand I am probably running lean. I am currently throwing a Check Engine Light and it is complaining about high voltage on 02 sensor bank 1 and 2 ( this was using a generic tester so I am sure the fault codes are generic). I am assuming that is because of these after market parts. I called a local tune shop (Pure Tuning in Toledo) to ask about UpRev and they quoted me $850. I cringe at that because I just bought a house and I have seen people get UpRev tunes for $500-600, which I am willing to pay. Is there a cheaper option for fixing the A/F ratios? Will the dealer adjust it for a fee?

I notice my Air Fuel Ratio ( AFR(m) ) hovers between 13-15 when driving, and when I let off the gas it jumps up to 29.x. This is coming from ODBII reader with Torque Pro app.

I appreciate any feedback.
