Your TPI and exhaust modifications should help performance, but don’t get so carried away that you give up everyday reliability. You should be able to hit the 350 hp mark with the computer and custom-burned chip. If you change fuel injectors, start with 22 lb./hr. units and go up only if top-end performance dictates more fuel.
Upgrading the camshaft will require the matching valve springs. Titanium retainers are also recommended. They will reduce the valve weight and prevent valve float. The trunnion bearings in the stock rocker arms are a known weak point. We strongly recommend a trunnion upgrade kit. Swapping in a set of full roller rockers is another option.
Got a dog (or well-trained llama) too big to sit in a seat? A good pet barrier can keep them securely in the back—away from your steering wheel and Stray Cats CDs. Most pet barriers offer a universal fit, with adjustable legs that secure to your vehicle’s floor and ceiling. There are larger options available for cargo areas of minivans and SUVs, along with compact barriers designed specifically for the back seat of a car.
This can cause a lean issue that creates a ripe environment for detonation, which will reduce horsepower as the computer senses the detonation and begins reducing ignition timing along with other adjustments to elimination the detonation. In these types of scenarios, just one degree less of ignition timing can cost you 10-12 horsepower. Hot, more vaporous fuel also doesn’t atomize as efficiently, which can negatively affect the injector spray pattern and how the fuel mixes with the air, both of which can cause a loss of power and performance.
