Hello, new to the ls1 field. I had cam, heads and headers installed... My tuner said that he dialed everything in at 80% throttle not 100% cause my throttle position sensor was acting up... Not put down 423rwhp. He said that once I replace the tps it will be at 100% does this sound right or does it have to retuned?

 

Is the TB opening all the way?

 

Yes, I also replaced the tps.
Does it need to be retuned?
