i own an '03 enthusiast automatic with 10,000 miles on it. last year at the drag strip i ran consistent 14.3 with 2.1 60ft bone stock. this year i added jwt pop charger, injen ses exhaust, ur crank pulley, max ground 7 wire system,ts ecu reflash and nitto 555r drag radials. went to the track last night and ran the same exact numbers as last year. wtf is going on. i actually dynoed the car and it shows a little less hp than stock. i love my z but i don't know what to do!!!!!!! any help would be glady appreciated!!!!

btw my car dynoed 216hp stock, after adding pop charger and crank pulley it dynoed at 222hp, then after adding the injen exhaust it dynoed at 216hp. i thought getting my ecu flashed would help but obviously it didn't. at the strip last night i lowered my rear psi to 20, took out brake light fuse, turned off tcs, gas tank 1/4, did a good burnout and launched at 3000rpm's. the dr's hooked good ,but when i drove around to get my slip, i still had run the same times as last year!! should i sell all my mods, get rid of the exhaust and add something else, send the ecu back? any info would help alot. my budget is maxed out right now so i don't plan on spending anymore money. also my a/f ratio looked fine. i just don't know where else to go.

oh well i guess i'm the only one on planet earth whose z has had this problem. maybe i should click my heels together 3 times and say there's no place like home and i'll wake up from this nightmare and my car will be running in the 13's.Damn!!

you know that you could dyno your car 10 times and get different numberes every time right? does your car feel faster?
Its probably your driving, outside temps, could be many things, anyway for what you added your times wont be that much better anyways, so the .5 second you might of shaved with power is easily lost if your run is not 100% perfect.
Am i making sense?

car feels the same to me. sounds more aggressive with the exhaust. my reaction times were .010, .049, .039. i did good burnouts with the dr's and launched with no wheel spin. the pa announcer kept bragging about my reaction times. outside temp was 60 damn degrees so it should have been running faster. bottom line i should have gained something for the money i have spent. i understand what you are saying about a perfect run. this is what i have been thinking about for the last 2 days. i don't drive in manual mode, i might start doing that. i will try different psi in the tires and different rpm launches. the dr's might have been gripping too much and causing my rpm's to lag behind a little, i don't know. do you think techno square may have screwed me on the ecu flash?? they could have just put a sticker on it saying it was tuned and just shipped it back to me. i hope not because $600 is alot of money for something like this!!! anyway thanks for the reply.
