j4nash Posted May 9, 2005 Report Share Posted May 9, 2005 You might have picked up like 30 hp at the crank Custom hand held tuners are junk. Spend a little extra and get a good custom tune. With a custom tune you could pick up like 20-30 hp so then with the air intake and muffler you might see like 40-50 hp at the crank Link to comment Share on other sites More sharing options...
