Hey, if you have a pi manifold, 75mm TB/Plenum, catted x, cat back on a 98 gt, what can you get by throwing the pi cam in? 10rwhp? and as with the full pi swap, a canned tune will suffice?

10-15RWHP from the cams alone.

Canned tune will help especially on the 96-98 ECM as they were the most conservative timing wise.

I'm really not sure, but you might encounter ptv clearance issues if you use pi cams w/ non-pi heads (.550" lift pi vs. .500" lift non-pi).

I installed stock PI cams in my non-pi cylinder heads and I didn't
have ptv clearance issues or coil bind issues.
I gained 10 rwhp from the stock pi cams alone.I bought my PI cams
brand new though.I'm happy with the gains.Seems to make more
power in the higher rpm's now compaired to the terrible non-pi cams.
Definitley get yourself a good mail order tune and you will see some
better power gains.I have a mail order tune on my mustang and it
work just fine with the stock PI cams.

Max lift has nothing to do with PTV clearance, and the NPI head will have double the PTV clearance of a PI head with the same cams.
