When upgrading to a larger turbo is it necesary to go with a new set of chips?

I take this to mean that you associate all Hondas with moronic ricers? This shows how little you know. I personally don't like Hondas, however I'll be the first to admit that people have done some crazy and technologically impressive things with them. I'm sure you actually could find better tech on some Honda forums, as there most likely isn't an elitist old-tech attitude hindering the progression of the performance envelope with those cars. You guys could learn a thing or 2 from the Japanese "tuning" scene. Heck, cars 1/4th the age of ours have already easily surpassed the performance envelope of the most built 951's around. Personally, seeing things like that makes me take notice and wonder what technology could be applied to our cars.
What's with the hostile attitude? At no point did I ever say you can throw any turbo on a car and it will run just fine. If you read my posts thoroughly (sorry, I realize I practically type novels & will try to keep it short
) you will see that I was simply trying to explain the function of a maf, and what the limitations are of switching turbos as the thread starter asked.
I'm sure they don't want to get caught up in the sh*tstorm. Saying anything out of the norm around here just invites a flame fest. Whatever happened to being open-minded?

(- If you are running a MAF then no.)
(- My headgasket is fine, and this engine has seen over 600whp.)
(- I don't know my AFR, but like I said before the car runs and performs just find. I also get very little Knock)
(- to much knock is very bad for any engine. But a little will not damage the engine.)
(but very, very small amounts will not damage the engine. If Porsche did not think the engine could handle it, they wouldn't have had the Knock sensor in the first place.)
Personally I love it when a guy with a stock turbo and another guy who doesn’t even own a 951 gives advice on someone else’s dime. My suggestion is to try some mods on these cars on your own dime and apply your cross over tuning techniques and then post your experience not your theory. Until then take some advice from guys who have done it, learn a bit about the limitations of the 25 year old motronic and CC design, throw away your copy of Maximum Boost, or just prove us wrong. Better yet, call John Milledge, Chris White, Scott Gomes, TT or Vitesse and discuss your analysis and they’ll laugh in your face. Until then, my signature still applies to this post.

Which explains, both, your extensive technical contributions and your significant involvment on the 930 and 911 boards.
This thread is not about the resistant culture to new information and technology. It is about preserving the ethic of proven systems. Most contributors here are gears heads to the Nth degree. What you won't find (at least from the older crowd you seem to be complaining about) is tolerance for unproven bull****. If you want make claims about how well your car works with a given part or set-up, back it up with dynos, AFR maps, photos. Bull**** like what Drifto is selling doesn't hold up without evidence.
Back it up or shut it up. It's simple. If you find better way to accomplish something or find a great part, show us!

Here is the only dyno I have of the car on my computer. It is at 12 PSI, the engine has produced more, and it's peak RPM is 10700. I am leary of taking it higher due in part to drivetrain harmonics and bearing longevity.
The engine is currently dissassembled for a bearing and ring switch-out.
The engine is tuned by myself using a Motec M400.
