Whenever you put ina new cam you should be using matching springs to avoid valve bounce and valve float. Both are good ways to destroy performance and the new cam. If it is a flat lifter cam you also need new lifters. If the car uses a MAF sensor you may be able to get away without a computer tune. If the car uses a MAP sensor only you will need a ECM tune if you expect to get the best results.
