[QUOTE="c6zhombre, post: 16047783, member: 76381"] I have a factory lower and 3.0 RR upper and make 18psi with factory manifolds. It makes 560 wheel with about 16 degrees of timing for 93 octane. Could it make more with more timing? For sure.....but pump gas is well, not good and variances, that you cannot test pump side, can and will happen. Stay conservative. I would think your 2lb lower and 3.25 upper would net about the same 18psi. I have 2.6 RR upper for the E85 tune that makes 22psi. This is run with 23 degrees timing and makes 714 wheel. The car has run this combo for almost ten years. It is fantastic performance, with great low and mid range TQ......it's on this tune 99.9% of the time. I only run the 93 tune on rare occasions because it's necessary. I don't like torco and don't recommend it. [/QUOTE]
