Is tune needed for PP plenum/throttle body?

[Black10thSVT]

I have a guy that going to tune my cobra for the 2.76. I also have a port TB and PL, but I dont think my gaskets will come in by the time he tunes it.

Should I wait to have it tuned after the TB/PL are on?
Or Can he tune it and then Put them on at a later date?

For u guys that have done this before what type of power increase will I get. See sig for current #'s. Only thing Ill be changing to are 2.76, JLT RAI, and the ported and Polished plenum and throttle body.

Thanks in Advance for anyone will to give constructive input.

This should not play a factor in your tuning plans. Porting the TB/plenum will get you about 8 RWHP+/-.

I agree with IronTerp, no need for a tune change. But there is also no need to wait for gaskets. Just use a little RTV and bolt the new stuff up prior to your tuning session.

This is what I would do.
