Any tuner who is tuning >1995 cars should be able to handle 94-95's if not look for another shop. From someone who has tuned thousands of cars, including many 94-95's, including our own - they are just not difficult to tune. You need the right tuning tools is all. All the SCT dealers we have trained have no issue with them. This is an old myth that started right when there was a transition from Fox bodies to 94's - they were way different back then. They are mod friendly too - our old 95 started as an NA car running 13.4's with H/I/Gears (it's a heavy convertible), transitioned to a KB blower on a stock 302, except for heads that went 11.2/123, the quickest KB around on drag radials back then, then it transitioned to a 351 with an 88mm turbo - made over 700 through a C4. Currently it's NA 420+ motor that has gone mid tens. Next season a Dart block goes in it with a 250 shot and better heads. It had been tuned with SCT initially, now it has a QH - OH, and it currently runs E85...
To use a QH, you need the QH ($249) and Binary Editor - the latest version comes with a dongle rather than the old software 'key' based security. These are sold right from the EEC Edtor/Binary Editor website For an NA car this may be all you need - for a power adder car, you also need a good wideband, one that does A/F, Lambda (all fuels have alcohol and you need Lambda readings and also MAF Volts - necessary for tuning. One of the tuner tools I previously referred to is the Zeitronix wideband - it does all that, plus one additional 0-5v logging source, TPS%, RPM and you can get a boost sensor and EGT sensor if you like. This and the QH make is EASY to tune any car - good data = good tune.
The Ultimate Tuning Guide walks you through setting up the tune, logging and applying the logs to the tune. And what to do if you have 'issues'. This book has been gobbled up by many shops,some of the biggest most popular use it and the others in the series, but it is simple enough for the novice.
Hope this helps!
