Cam / Tune question

[blazer427X3]

I might be replacing the cam in my car depending on how it looks but I am fairly sure that a lifter failure caused me to wipe a lobe.

Car is a 2002 Z06 with an LS6 engine.

Right now the cam I've got is a TSP 233/239, 595/603 on a 112 LSA and I like it.

I can save a worthwhile amount of $ and get my hands on a CompCams XER 281 HR locally. Specs on this cam are 232/234, 595/598 also 112 LSA.

It seems to me that the specs are close enough that there wont be a noticable difference in performance but will the small differences between the two cams require that I have the car retuned ?

Other mods are : TSP 2.5.5 heads, Patriot Gold springs, longt tube headers - X Pipe- no cats-stock mufflers, BBK intake, ported T.B., Vararam. Previous owner had the car tuned when he did the mods.

Thanks.

The two cams are very similar and should maintain similar performance levels. I do not see any real reason to have to retune the computer but I would discuss this with your chosen tuner as they will know best.

Thanks for the reply ! On your advice I called my Tuner. He said that WOT settings will most likely be very close. P/T settings will probably be where he spends the most time dialing it in.

Glad to hear you got it worked out bud.
