Wester's

[daniej1]

Thinking of purchasing a performance programmed computer from Wester's for my 2000 K2500 5.7L truck. What add ons should I install before buying this product that will get me the best perfomance for the money?

If you are changing tire size, do it first. Other than that the Wester's will adjust itself automatically for any intake or a exhaust system changes. If you get a supercharger or make a radical cam change in the future, it's only a $45 shipping/reprogramming fee to update it.

What modifications are worth the money prior to purchasing the Wester's computer? Headers or camshaft seem like pretty drastic changes. I was thinking of buying the larger throttle body spacer and the Granatelli? mass air flow sensor first. But would consider the cam and headers if they would make a big difference. I've been told the Wester's tune will add 15-20 hp alone. How much more could I expect from adding the other stuff?
