Hi there. I'm thinking about getting 1994-1996 celica gts because of the look. but I'm not too happy with stock 135hp. and my question is are those cheap mod Chips/sensors really give u +20 hp? or at least +10 hp? I found alot of those selling for $2-$20 on Ebay.

If they don't really work then what's the cheapest way to get to at least 160hp without noisy performance exhaust.

THanks

I bought a chip from ebay for my o1 gt for $15. all it is is a resister that plugs into ur ait sensor. it tricks the ecu into thinking the incoming air is colder and more dense, thus adding more fuel.
In my car i noticed a little differance. but i also have a cai.
I am happy with the chip, it took off about one tenth on me et

Those chips on ebay are a joke. You could just save yourself the hassle and go to radio shack and buy a resistor there. I dont see how just a simple resistor could knock one tenth off a quarter mile run.

To get to around 160 your going to have to get a cold air intake with a high flow filter and atleast a catback exhaust. I would think that they sell one that doesnt have a fart can on the back to make your car sound noisy.

thanks for the replies. ok, so I guess those resister thing maybe stupid but they are selling for $3 anyway.. but what about those ECU unit? do they give 10-20hp? there is one called "ProBoost Platinum" for $30 on Ebay. Does anyone know if it really works? or is there any better ECU unit that really works? and how much is it?

Thanks

headers intake and exhaust are basically the thigns thatll get u close to that #, try changing ur ignition setup and stuff, if u want an easy 30+ horses look into camshafsts, ull have to upgrade ur ec tho .....
