I have a 1995 5-speed SC. I recently did exhaust work, SCP CAI, C&L 73mm MAF, BBK 70mm TB, 5% pulley and a 180' Thermostat for modifications. Those modifications are the extent of what I am going to do. I get 15 lbs. of boost at 2,500 rpms and I'm sure I'm hitting around 17 lbs. at 5,000. The car has had a complete tune-up including new Motorcraft plugs gapped to .050
I put the 5% pulley on last and I started to get some detonation. However, when the car is cold it runs great and pulls to 5,000 rpms real hard with no detonation. As the car warms up it seems to run fine but gets some detonation and doesn't pull as hard.
I know that when the car is cold the timing is way advanced and the fuel is set to run rich. Do I need to consider a tuner or a chip and will one solve the detonation problem? The EEC seems to have tuned some of the detonation out but it rears its ugly head enough for me to want to fix it.
Any suggestions?
Thanks,
Bob
