RE: steeda timing adjuster install
ORIGINAL: sweet99
I always thought the '99 GT had 9.4:1 compression also. Where can I find that nit has less? Also does the Predator allow timing changes from 2000-4000 and from 4000 to 8000rpm's? That is how mine was and it did not allow the timing to be raised by degrees but by a percentage with the max being 10%. If you got a manual check it out. It was also a percentage of the STOCK timing and only at WOT. The steeda adjuster works from idle to redline. mark

2001+ have more compression (9.4:1) so they can't take as much timing.� I added 2* to the perf tune for now.� I'll try 3 next time I'm messing with it...

The performance tune that comes with the Predator adds very little timing. If you have the tune that adds 10% timing in 2 rpm ranges it is adding 1* at 4K and 1.6* at 5K. I had to use the adjuster with the Predator tune because the predator tune was so lame. I added 6* on top of the Predators 10% increases and no knock with 93 octane. Mark

I bought a used Predator tuner for $150.� If you are patient you can find a deal on ebay.� I advanced my timing via a performace tune in less then 5 mins 
ORIGINAL: jusnkrisit bolts right up to the crank pulley. then you relocate the sensor to the pulley. takes about an hour or so to do. it stays on and you are able to advance and retard the timing. i dont know much about tuners, but form what ive heard you can advance the timing. timing adjuster goes for about $150.
