I have installed the Fab-Speed exhaust(not the headers) and had them re-flash the ECU. I am now considering adding the IPD Plenum and I spoke to Fab-Speed to see if the re-flash would handle the increased air flow. The response was it may make the car run too lean. What has the experiance been with those of you who have added the plenum with a ECU re-flash?
Plenum
The plenum is the piece that goes between the Cayman throttle body and the intake runners. The factory piece is a long black plastic tube with a divider down the middle. There are aftermarket replacements which are designed to allow the air to flow easier/faster into the engine and increase horsepower and torque.

Bit strange, surely you'd just get the ECU re-programmed again AFTER installing the plenum ?
Configured for ALL your mods....
I'm also seriously thinking of adding the fabspeed exhaust and would also look to the do the plenum, think I'll leave the ECU remap until after I've done both of those and fitted the LSD.

LSD - Limited Slip Differential
A limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely– the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use however, such as driving off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

IMHO the person who told you that is an idiot (PC rephrase: "the person who told you that is not knowledgeable about engine control software").
Your car has a mass flow sensor that measures the mass of the air entering the engine. The engine computer will supply the correct amount of fuel for the measured amount of air. The plenum will increase the amount of air, but so would driving on a cold day.
If the flash won't work with a plenum, it won't work on a cold day, either.

I also see an improvement, I can easy spin tires on second gear ! And I have a modded croc. Car as faster even after all the mods ! A Dyno run can testify that but unfort. not one around here.

Where do you buy the plenum, would like to get one to go with the Evo cold air intake.

There are a couple places to get that .I believe there is a Rule here on this forum that does not allow me to Promote the One I support but maybe I can say I am really Happy with My Softronic and Scott . do some searching here on the Plenum subject and the answer will hit you right on the head .. its a no brainer decision in my personal opinion ..and it works

The IPD plenum (even without software) has proven to be the single best mod you can install on a Cayman. We've posted countless dynos, with both modded and unmodded cars and all have yielded great results. Independent customers have posted their dyno results and we've even seen European Car Magazine dyno test the IPD plenum always with great results. I thought the debate was over. But just in case you need a recap here are some dynos for your viewing pleasure. Some of the dynos also showcase our new “Competition IPD Plenum” with a true 82mm Throttle Body, which will be available soon.
While conducting your research you will probably find that there are members who have pledged their allegiance to their respective board sponsors and will never surrender the fight. After you conduct your “searching here on the Plenum subject and the answer will hit you right on the head .. its a no brainer decision in my personal opinion ..and it works”
Please feel free to give me a call with any additional questions or concerns.
Cheers,
Greg
The Dyno above was conducted on a Cayman S that was already equipped with a FULL Cargraphic exhaust. The IPD Plenum Intake works very well when combined with a high quality free flow performance exhaust.
