Please help on some ECU questions!

Welcome John. Unfortunately the chips out there won't really yield any horsepower gains without also changing the intake and/or headers. GIAC (a very reputable tuning company) has dynos that show that its chip, plus an EVO air intake will yield about 18-20 hp's at the wheels I believe. Might want to look towards that route.
However, it's not cheap... we're talking $1500 for 20 hp's.

Good luck!

Hi John,
I agree with Jwocky.
There's been quite a bit of discussion on this board about chip mods. I too asked the question. The concensus appears to be that a chip mod by itself is not worth the outlay because the performance improvements are minimal.
The greatest improvement you are likely to see is swapping the engine for a 3.4 or 3.6L from a 996. that's a big job. Or look for a turbo upgrade.

Ultimately it is your boss's decision, but I decided I would save the pennies for the next Boxster once this one is paid off......
