I am new to the tuning aspect of working on these two cars. One is a '99 mustang with a security issue. Apparently the sn95 mustangs are known for this. All it needs is to have the pats deleted or reprogrammed. I know there has to be someone that can either warn me how hard and/or easy the actual process it is or maybe has done the process and can maybe give me some pointers or maybe give me a guide or help along the process would be beneficial. I'd finally have it back on the road and finally driving something mine. the other car is a bit more involved as it is a 2.4l turbo getting some work on as far pushing more boost. That car I'm not too worried about as I'm awaiting bigger throttle body and a ported intake. My cams for that car did show up so I'll have that keeping me busy next month. the mustang and the jeep are priority as this moment. Another good reason why I'm trying to do this myself mainly to learn a new skill set and also, we on a very tight budget. Any advice is greatly appreciated, and I look forward to reading the responses getting to learn something new and set myself a good challenge.
