Currently running an NA tune from ICEMAN (Steve). I adjusted the TPS while the car was running and it really likes the .49V I'm running now. Spec is .45v-.55v so I'm happy with that. I don't have a timing light so that won't be an option at this point, but I'll be throwing the stock intake manifold back on hoping it will help with the low end a bit. The one on there now (was installed before I bought the car) has a huge plenum and shorter, fatter runners. Combining the 248 cam with the high-rpm designed intake manifold absolutely killed the car's balls below 2k rpm.vas13hatch wrote:3 teeth ccw is 3 teeth advanced. I dont think it would run the other way. I have this swap and it does feel like the low end lost a little but seems to pull harder and harder from 3k to around 5500-6000, I dont like to rev it out much more than that. If it's stumbling off idle get a timing light and adjust your actual timing, or just experiment and turn the distributor a little till it runs better. If that's not it then it's probably fuel/vaccum related.
Consider getting your ecu tuned. These cars were tuned from the factory for emissions not power, a tune can make a great difference in power.
