ATI plus 2% R53
Used less than 10 hrs.

Too much boost/IAT at 8k rpm

Perfect for street or stock redline.

SOLD

Too much boost? Please explain, was thinking of getting either the 2% or the stock one that really is just under a 1%.

RE: ATI plus 2% R53
The factory ECU starts complaining when you go over 20 lbs. boost. Depending on your pulley combination, you can go over this number. I only have a 15% underdrive on my supercharger, but my boost gauge has indicated a peak of 1.2 bar, or roughly 17.40 lbs. boost, at top end. This will increase as you go to a 17% or 19% supercharger underdrive pulley, 1% or 2% crank overdrive pulley, etc. Your total boost will also vary based on altitude.

Its the factory MAP sensors in combination with the ECU. The sensors only read to 21psi.
