if the Dinan chip is installed alone without CAI or exhaust, what kind of perfomance increase can be expected?

I would double check on there website, but I believe the Dinan chip is not a real performer and really only raises the rev limiter and removes the top speed regulation at 155, Josh

From past posts on the board I believe that power chip is the best bang for the buck.

if you go to dinan's site, even they admit that they're not gaining any power with stage 1. Only improving throttle response and eliminating the speed limiter.

Mike,

Good to see you still posting. I've been pretty discouraged by the material on the board over the last few months, making me frequent it less and less.

If you were to do it all over again, would you have still done all the engine modifications?

Short answer, Yes, long answer in pm!
is it worth it, from a $/hp perspective probably not, but i'm happy!

Depends on octane (91 v. 93), but Powerchip claims hp and torque gains of 6-11 each.
