Help with performance chip etc. Hi,
I have a 1998 Z28. I recently installed a slp Cold air induction and the SLP LoudMouth exhaust. Is it necessary to buy a programmer or chip to fix my air ratio's?? I dont want to hurt anything in my LS1 by not doing this. And if so any recommendations as to what I should get.
Thankyou

a chip is just that a chip that needs to be flashed separatly...flash proms the chip is permenantly installed on the board and gets rewritten over via the obd2 port under the drivers side dash.

^^^ see sticky about best programmer...
Basically you have 4 choices:
1. Mail order tune ... perf gain depends on who's doing it and your mods... but it's not an exact science
2. Dyno Tune ... perf gain depends on who's doing it and your mods ... more exact but can't change later yourself
3. Handheld units ... ok for very minor bolt ons... most canned tunes are a joke and will only help a little (though some cars take to them better than others)... examples include Predator and Vinci Handhelds
4. Full tuning suites... you learn and tune your own car... can make changes at anytime but there is a learning curve

The handhelds are easy to use... but I personally wouldn't waste my time with them... (unless you can get one used, just make sure it's unlocked)
I would hold off until you do more mods and then go w/a dyno tune

partially because of price... but also because the canned performance tunes are just guess work...
you may apply a canned tune and your car may ping like a sonabitch... or it could drop a tenth in the 1/4 mile... it's a tossup
Used they're great for changing things like fan settings, shift points, gearing, etc...
But for the price of buying one new... it's not much more to have a dyno tune (best solution is to get a tuning suite and learn to tune yourself but that's not for everyone)

Just start mashing buttons like me...I haven't blown up anything...yet. 
Our tuner does not just use canned tunes. We have 8 preset programs (from stock cam performance tune to a supercharged cam program) and then you also have the ability to tune your fuel and timing curves, as well as change injector sizes and constants. All you need is a decent scan tool to read 02s, timing and knock retard and you can dial in the vehicle. This eliminates the hit or miss of other handheld programmers. Ours is truly a tuner. Unfortunately, most people are under the assumption that you can only plug in a preset and your done. They are not using our tuner to its full potential. Give us a call if you have any questions. Also, we have the only handheld tuner for 98 cars.
hand held tuners? I have the Vinci High Performance Tuner. It is matched to a preprogramed set of parameters for their cams. I am currently running the 062 Vinci Asp-Kicker cam. Push a button and your tuned. Whats so hard about that? If something goes wrong you have a crew of experinced people backing you up.
