Yeah, I know I guess I should have waited. But every upgrade I do I tell myself this will be the last one. But as far as the ECU goes, remapping the timing, fuel ratio etc. should not effect mods like the lightened underdrive pulleys, flywheel , etc. They make their power by reducing weight on the crank. The general rule of thumb is that for evey pound lightened off the crank will result in 2.7 hp gained (this according to Unortodox) I'm really looking forward to installing the Zex kit. I've heard nothing but good things about it. I was going to go with a wet kit like Nitrous Express, but an performance mechanic told me that there is always a chance of puddling, and he has installed well over a hundred of the ZEX kits and in his option is the safest on the market. I'm starting to ramble.."everybody needs to believe in something, I believe I'll have another beer."

I think I am probably done tweaking my engine just becasue I have exhausted all of the possible N/A modification components for our engines. I would like to do more, but have not found anything out there that I do not already have. (still waiting on the Arospeed headers) I have the Ingen short ram intake with a custom cold air setup that routes air from under the front bumper to the intake filter, as free flow exhaust as you can get with a costom dynomax high-flow cat and a magnaflow muffler (which by the way sounds really great, no "ricer" sound, just an nice deep note) I have an MSD 6300 SCI ignition with Tach adapter, NGK wires and Denso Iridium plugs and of course the Jet Chip. I can't find a good throttle body yet, and I'm looking into underdrive pulleys and a possible cam. I will have the ZEX kit before summer. I posted my car here but it hasen't showed up on the member rides yet. here is a link to my car domain site.....http://www.cardomain.com/id/longshank

I just got the Jet Performance Chip upgrade and couldn't be happier. The thing about this upgrade is that you do it as your last upgrade outside of nitrous. When you send your chip in, you give them a list of your upgrades, and the taylor the chip to that. I got about 15 wheel HP. Right off the bat it was the best upgrade I've done - BAR NONE. Better than my intake and custom exhaust combined. The Venum 400 has gotten terrible reviews and will reduce your gas milage by at least 2-3 mpg. There is one bad thing about my upgrade. You have to mail your ECU in, and i couldn't afford to be without my car for the four days it took (I sent it in 2 day, they return it overnight) so I bought an ECU from a junk yard and tested it for a week to make sure it worked. Jet said that because it was not the "origional" ECU there would be no warranty. I said go ahead and do it. I can run 89 octane with no problem and my gas milage is the same as it was before (even though I floor my car quite a bit more now). I paid $380 for the upgrade and $100 for the second ECU. They even said I could run up to a 40 shot of nitrous with it without having to retard the timing! That is what I plan on doing next. Hope this post was a help.
