I thought stock sensors would only go to 22-23 psi? What kind of dyno did you run on?

He should know from the logs if you have a boost leak or not. Any good tuner can spot a boost leak from a mile away.

I'm either doing nitto nt05's, 01's, or direzza star spec 2's.
I had nt05s really liked them, this spring I'm getting NT01s cause I'm getting a smoking deal on them

nah on dyno wouldnt go higher than 22 and yeh he told me its a leak somewhere im guessing a coupling in ic or the intercooler itself may be cracked. im on stock sensors and in the street off the dyno it spikes 24 psi, i asked about the sensors told me he is reading them fine so that isnt my problem and they arent blown, we unpluged electronic boost controller and had open wastegate for it to spike boost floored the car and it didn;t go past 22 - 23 psi, should be way up there, and should i go up in tire size? im still on stock tire size got some bf good rich sport comp2
