OK, two things. First, is it normal for this car to rattle when going very slow in first gear? It seems that if I need to edge forward very slowly, the car feels like it's going to come apart.

Second, has anyone done Dynas before and after an exhaust, CAI, and flash upgrade? I'd like to know the results.

Third, does anyone know what effect the mods will have on fuel efficiency?

HP, Torque curves, stock 143 WHP and 177 BHP

ECM retune, stock between 7 - 10 whp 151 - 154 WHP 192 - 196 BHP

ECM retune with only intake mod Add 1 - 2 WHP to the ECM stock 155 - 156 WHP 199 - 201 BHP

ECM retune with only exhaust mod Add 2 to 3 WHP to to the ECM stock 156 - 157 WHP 201 - 203 BHP

ECM retune with exhaust and header mods Add 5 - 7 WHP to the ECM stock 159 - 161 WHP 207 - 211 BHP

ECM retune with intake and exhaust mods Add 4 - 5 to the ECM stock 158 - 159 WHP 205 - 207 BHP

ECM retune with intake, exhaust, and header mods add 7 - 10 WHP to the ECM stock 161 -164 WHP 211- 216 BHP

The person who did these dyno's used Long tube headers, I believe the long tube will give you 3-5 more BHP than shorty's

Thanks for the info. Couldn't find the dyna information and probably could have searched for the noise issue, but threw it in while I was asking.

BTW, what did the mods run? I'm curious what it'll cost me to do all this.

Thanks again.
