but what do you mean tuning?
what else can i manually tune after the chip
Best way I can describe it....and someone correct me if I'm wrong....pop in your new TT chip. It should be set up to like 20/18 timing on 92 octane and 16-17 PSI.
Go to your local drag strip. Turn the boost down to like 12....make a pass. Watch for knock. Don't worry about how fast the car can go at this point, your main concern is ensuring you have an adequate fuel/air ratio. If you see ANY knock at this point stop and figure out why.
If none comes up then up it another lb....make another pass...if no knock then up it to maybe 15 and maybe add a little fuel if needed. Make a pass. If you're doing it right each time you add boost you should be going a little faster thru the traps.
Now if all checks good and by the time you hit 16 you start seeing knock, then back off. You can try adding fuel via the chip and Scanmaster and seeing if that helps. if so, proceed. if not then back off.
What you want to do is shoot for the highest mph you can go thru the traps w/o any knock. And also the highest boost you can achieve w/o any knock. If you have more air than fuel you'll go lean and that's where knock starts happening. That's why it's important to start off small, so you can see where it's weaknesses are.
Now if anytime you make a pass and knock is detected, you need to let off the pedal and figure out why. Could be false, could be real. At the top of 3rd gear the Scanmaster should be in the 780-800 range. If the Scanmaster reads anything lower than 780, let off the pedal.
I don't know if you have upgraded your fuel pump and hot wired it or not but if not then now is the time. Your engine needs a good fuel supply to keep up with adding boost. The stock pumps were crap and are probably worn out by now, plus the voltage drop in the stock wiring is what warrants the need for the hot wire kit.
As a final thought I myself have always been told if I wanted to run any boost over 15 I'd need an alky kit or race fuel but some here have claimed they've gone more than that on pump gas.
