I can't wait for the outside temps to drop here in Orlando. I basically have about the same mods as you and as far as the Caliber SRT-4, if they don't get their ECU upgraded, they are a slug. I went to a dyno last week and saw 2 guys, who were best buddies, one with a Neon SRT-4 putting down only a measly 212 whp, and his buddy with the SRT-4 Caliber putting down 261 whp! Well on their way home, they did a roll from 40 and the Neon walked him! Go figure? Those Calibers have their power held back in 1st, 2nd and 3rd until the tune really opens them up.
