You asked about a chip...Hypertech has a programmer for 99+ models that you could get, but I'd suggest getting a professional tune instead. It will be a lot cheaper and much more effective.

Once you have the all the bolt ons done, all you need is TR6 spark plugs (less than $2 a plug) gapped .035 and you are ready for a small shot of 50-75 shot of nitrous! That'll probably run ya about $800-$1000 to run safely. When done right, nitrous can be just as reliable as a Powerdyne sc. Just thought I'd throw that out there as a option.

Viper04af is the guy with 456rwhp, but he is (well...was) running 18 psi on a MP-T70 turbo on a fully built motor.

Also- 430 and 445 on stock long block might happen- but how long will it hold up??
