Ok im confused, when i put turbos and superchargers on my car, they run slower then if i did just pure NA parts and weight reduction and port and polish upgrades?? so which is better high horsepower and high PR or fast car with no parts except for weight reduction and port and polish?????

Try test n tune.. and upgrade the turbos on ur car lol.. a combination of both will lead to faster times :roll:

You're obviously installing the wrong parts onto the car. What type of car do you have, tell me that and ill get you a parts list, once you hit a level around 30, all you really need is weight redo and port'n'polish to level 10, that should leave you PR around 1000 or a little less, any higher than 1000 is just a waste of feul/nos. Once you got weight redo and pnp, dyno to 100% then tnt the car and you'll be fine, hope this helps

my cobra has like 550 pr and it's doing high 8's low 9s with level 34 and only pnp/weight on top of the parts

i run 8.3 with just weight reduction

if u have lvl 10 weight reduction u dont need nethin else

but suspension of course
