The Hurricane stock muffler 270 flash will have more predictable boost control and will make more Hp with a three bar map sensor.this year many guys decided to add a three bar sensor to the 240-270&290 performance muffler flashes. This often created an overboost condition and subsequent boost cut. As a result we created all new flashes for the three bar map sensor to be used with performance mufflers. The new three bar performances muffler flashes are 240-270&300hp.

Whats the highest tune for stock muffler,290??

Nope. 270 is max with stock exhaust.
