Ok....I hope I get the answer before september 20
basically I need to decide between an ECU or the APEXI cat back.
can only afford one or the other.....
Which do you guys think is better for me?
cause both are about 400$

I am more to the ECU...
what do you think?

I would go for the ECU if you already have some type of exhaust system. You should see more gains.

Espcially if you have a GXE model. It would remove the speed limiter as well as the gains would be increased.

I would also go for the ECU right now while you have the cash. I was slightly more impressed with the ECU mod than with the catback system on my Max.

Remember you have to run 92+ octane with the ECU mod.

JWT will also do an exchange with your ECU so you'll get the new one before you have to send your old one back.

make sure that it is the JWT ECU !!!!! I have a 95 SE auto and just by installing the JWT ECU by itself and no other mod it is really a eye opener. Make sure you always use high octane fuel !!!!! When I was totally stock from a dead stop I could not chirp the 225/55/16 tires that I have, just adding the ECU I was startled the first time I stomped on the gas my front wheels chirped and started spinning a little. In fact using my vericom performance computer I was able to measure a 10 fwhp gain with just the ECU about 15 hp at the crank. I then did a Homemade intake like the Stillen or JWT and that made very little gain that you do not notice it, infact I was only able to measure a 3 fwhp gain on that. The next biggest gainer in HP and the next mod you should do is the Y-pipe. I installed that and it increased the HP another 10-11 fwHP. These are the only 3 mods that I have in my car right now and the exhaust is still very quiet with the y-pipe since I have the stock exhaust. If you have any questions let me know and I will try to answer them the best I can. Good Luck !!!!!!!

Julian: I just read you reply and cant believe that your car only chirps the tires. I have a 96SE Auto with the 225/55/16 withe the stock tires and I can spin them very easily. The only mods I hae are JWT intake and Stillen ctr pipe. I can even spin while driving slow, and whem Im going about 25/30 mph and floor it, the tires chirp when the car downshifts. You might have a problem-Jason
