electronics? are you talking a new chip? i would say a claim of 30hp on that would be accurate. if you are gaining that with a new fuel map, then i would guess an upgraded exhaust would give you another 5hp, maybe less if it wasnt that restrictive to start. carefull of big claims by manufacturers. a 1 3/4 inch exhaust upgraded to 3" might not give you any improvements over stock, might even hurt performance. however, if your exaust is the restricting factor, ie, performance heads, turbo, intake...the 3" exhaust might give you another 30hp.
