    I recommend the $200 ported manifold (8HP), and the milling the heads to create ~11:1 compression ratio for $175ish (7HP). Together that is 15HP for less than $400. That is good power/dollar ratio close to a rotofab or vararam intake. I wish I woulda done their ported manifold instead of my ported FAST LSXr. Yes mine made 12 more HP, but not worth $1200 for only 18HP. Check out the difference in torque between my car and that stage 2.5 write up you asked me the question on. Most of that difference is our cams. 15 ft lbs torque is from my milled heads and LSXr combined. Our HP peaks might have only been 15 apart but my HP and torque peaks comes in 500rpm earlier. Just my 2 cents...

    Even the torque/power down low will improve. The cam they put in mine is a 227/239 .614/.624. I have a friend in my G8 club who personally did a DOD delete and installed a stage 1.5 Livernois with a yank 2800. His runs rougher than my set up. When he drove my car he couldn't believe that I had much more aggressive cam and stall (10 degrees duration and .025" more lift). He said mine drives like stock comparred to his rough rider. His also makes 30 less horsepower and 30 less torque. The difference is not in the companies or the cam, it's in Steve the tuner. He is a magician. He might be antisocial and come off arrogant, but he's actually a softy who is gifted in his art of tuning. If I knew my application was going to end up being this tame and streetable, I would have put a bigger cam in my car like a stage 3.5 or 4.0, something with 5 more degrees duration and little more lift to squeeze out another 8-12HP for free.

    Cool. You won't be dissapointed. Their stages are not as extreme as most of us think. The stage 3 they installed is truly badass, and most important tame as far as driveability when at low throttle and in traffic. Steve knows how to tame the beast below 25% throttle. The stage 3 cam will get you an additional 10-15HP without a single dollar more.

    Stall answer. Once Steve tunes it at VMS, it's like stock. Gas mileage is down in the city, but no change on the highway.
