iam thinking of going with a AEM over the pigyback greedy stock ECU set up
has anyone use one.....if so any prose/cons


ps looking for a good surpa part dealer thank you

First the AEM EMS is the best ECU on the market hands down, second go to Intensepower.com we specailized Toyota Supras MKIII & MKIVs

i wouldnt say its the best...there are a bunch of other companies that make amazing ecus whether its piggyback or standalone, the aem ems is definitely one of the most user friendly systems out there that does teh job well....but there are others :ph34r:

HKS has been messing with Supras since they came out, and are well tested. Standalone ECU's are a royal pain unless you have full access to a dyno and you have someone that knows how to tune it correctly so you don't go lean... If money is no object, you'll get more gains out of the standalone though...

electromotive ,dyno,tuning=time to check yer nuts,cause you're goin fer a ride!
