    map sensor, check with OS upgraded to 3 bar via scanner what your map sensor is ready at key on engine off... are you getting any codes or emergency power?

    You need to set the MAF codes to fail on first error and set your MAF fail freq to 0 Hz to properly activate SD with HP Tuners. You want your MAF to fail instantly when keyed on and cranked the first time.

    ...and everything Sultan said about the MAP. That P0106 will need to be addressed.

    Is the VE even close to right? Did you copy/paste your 1 bar VE to the 3 bar?

    Definitely set the codes to fail on first try.

    With the 3bar tune, are you doing a write to entire or write to calibrate?

    I figured that.....

    You need to do a "WRITE TO ENTIRE" to apply the custom OS(3bar).

    After you change the OS then you can use the write to calibrate function.

    The car runs with that 226/229 camshaft and 60lb injectors on the stock tune perfectly?

    Post the tune you saved as your "stock tune".
