Upgrades are usually done in stages. Each level will provide more performance than the one before it. However, they will also be more involved and expensive. The first upgrade we recommend is tuning the computer. This involves changing the fuel and ignition curves to optimize performance. A good tune can gain up to 40 hp on a stock engine. (Any significant upgrade will require re-tuning the computer.)
Unless your pet is a kangaroo, they might struggle to get into a vehicle with a high deck height, like many trucks and SUVs. That’s where pet ramps come in handy. They’re available in a wide range of sizes and most fold compactly and can be stowed away, so you can bring the ramp with you.
Fuel injectors and the rails that hold them are just as susceptible to heat issues as the carburetors they replaced. Located on top of the engine, fuel rails see a lot of heat exposure. On late model vehicles this issue is further compounded by how compact and tight modern engine compartments tend to be, along with the factory engine covers that are all the rage these days, trapping even more heat that can be transferred to the fuel as it flows through the rails on its way to the injectors.
I would like to get about 350 hp out of the new engine and run in the 13s. Is this possible with my combination? Your crate 350 should be okay for use with a TPI system. We recommend checking the engine’s camshaft specifications. Most “computer-friendly” cam profiles are no bigger than 214-222 degrees duration at .050 and .450-.460 inches of lift with 112-116 degrees of lobe separation. If the cam in the new 350 is much over these figures, you should consider a different camshaft to ensure compatibility with the IROC’s computer.
