You are right, a fully programmable chip is a better solution when seeking outright power... , but everything has its pros and cons. The reason i like a piggy back chip is that Toyota spend millions of dollars and thousands of hours gettign things like cold start, idle and closed loop running perfect. I would be naive to think a tuner could get these things as good as Toyota with a day or tuning. I just want the air/fuel mixtures changed on Wide open throttle to give me more power and more responsiveness when i hit the accelerator. A pigy back chip does this. I used to run a Motec in the STi and the gains were awesome! But we could never get it idling or running as smooth as the stock car. I suppose different chips for idfferent applications. Thanks for the response though, greatly aprectiated.

What are the gains like and who did you get to tune it. I prefer a Dyno tuned solutuion

Hi Guys ok.. first official post. Bought a black 03 Stivo a month ago after going from a heavily modified STi. Small change, but financial responsibility has caught up with me. Have changed the handling with Koni/whiteline and 17" wheels also had a LSD installed. I have ordered a CAI and looking at a magnaflow muffler (If i can find one with sufficient flow but without the drone) to improve power and drivability. I was wondering what people's experience with a piggyback chip (unichip) with the above mods. With a turbo car the chip has a huge gain with its ability to control boost, but I am not sure with a NA car like the stivo. In the graph below, it looks like you can get some gains but are they worth the $1000 for the chip. Any real world experience would be great. http://www.airpowersystems.com.au/unichip/...ota/celica.html Gipper

My 03 is booked in Friday 17th to get the 1st to 2nd gear change fixed. Like everyone else, over 7,000 rpm I cant select second gear... although second to third is fine. If they don't fix it it will keep going back under warranty until it is fixed. Love having a warranty on the car... love it!
