12.5Psi Tune, But Read 14.5Psi On Gauge

[TXR05]

as title says, I'm running a 12.5 PSI tune through chip torque. When I'm on full boost, its reading 14.5 pound. It does this too on the 10 PSI tune, But reads 12 PSI

Am I over boosting, or is it just the cheap gauge I have ?

I was given what was said to be a 15psi tune but logged later elsewhere spiking at 20psi!!!

Just get it data logged and checked

What gauge do you have? If its a supercheap or the likes I'd just bin it,

[TXR05]

Auto meter I think.

If your 10psi tune reads 12 and your 12.5 tune reads 14.5, obviously theres a 2psi difference.. Check all the boost gauge wiring etc.. and if nothing wrong with that then chuck it on a dyno and see what that says.. Bin the gauge if its the cause, or ask the tuner wtf?

You can log yourself if you have an XCAL device, straight to a laptop. Let me know if you want to see the pretty graphs I've made with mine (boost spikes and 0-100 times). The car can tell you the boost itself!

I have china spec gauges that read WAY over once the boost is up there. Real boost loaded up in 5th on dyno was 17PSI, gauge reading about 25!

If its a 12.5 psi tune, then it is probably referring to the boost made at peak power, which, if you havent had an actuator done, is likely to be peaking to ~14 psi in the mid rev range to bring the torque up.

If you're worried about what happening take it back to the tuner. They have much more sophisticated gear than a ~$100 boost gauge.

I'd say its your boost gauge. I had the same thing with my old boost gauge, it was a fake Defi gauge. now I have genuine Defi gauges, very VERY good quality gauges. also very expensive. but its dead accurate now.

steve - which setting do you use to log boost? also how do you do 1/4 mile times?

pretty graphs please

Have you changed anything on the car since the tune like intrcooler or highflow cat?
