So I bought this 2015 a week ago, car is mildly modified an I am trying to figure out where my next step needs to be. Currently the car is on a 93 Ortiz tune, previous owner bought one of their packages. Colder plugs, thermostat, map sensor, air raid cai that now has a K&N cone stuck to, lowered on H&R springs, and mufflers have been deleted. I have all stock parts that came off the car, I just did oil and trans fluid change. Unfortunately the car met a deer while on the way home with it, so it has a date with the body shop. Car also is sitting at 93k miles and I've found an oil leak that will lead to a romantic time at the dealership to have timing and motor resealed. I have absolutely no idea what the car is making power wise, unknown times, and if the tune is revised at all. I plan to drive the car fairly often but have another daily. I bought it to have fun in while being DD friendly. I would like to make a reliable amount of power that will also be fun on the weekends for Mexico. I've read through probably 50 or so threads and have been inconclusive in what to do after having the previously listed issues corrected. I know PTU and rear diff fluid are next to be addressed, but for a power aspect I'm lost. I've seen downpipes, intercooler, hpfp, and piping being some things to do to net respectable gains with the cars, going to E30 is something that intrigues me as well cause going full E seems a bit of a stretch on stock turbos from what I read. Any input is appreciated. I would like to think 450-500whp and max of 550wtq is about the top of where stock motor reliability ends.
