Billy, Byron has one on his Challenge car. Yes, you can hear it for Miles. Make sit hard sneaking in the house after a night out with the boys  True, in the original Challenge series you were only allowed certain mopds and they all evolved around F-parts. You can actually order the Challenge exhaust for $ 1000 for your Ferrari dealer. I have to warn everybody though, it is loud! | ||

There is mis-information here. The last 348 made had the best ECU's that was the spyder. Challegne cars that were earlier than this that raced used the spyder ECU's AKA Challenge ECU. No Ferrari Challenge car ran the challenge race with aftermarket chips. That was not allowed. Aftermarket chips are alot of hype. Ask Landshark on this list that is a chip burner tuner. He will tell you the truth. The last ECU's are the only one avaialble OEM Ferrari. You can't even buy the old ones anymore. They have the best tweeks and a rpm limit 200 rpm over the original stanard in 1990 in the 2.5 motronic. This rpm limit was one of the most significant features. The challenge Exhaust the race one and new ECU with wider wheel offsets made these cars the quickest. The exhaust in the streetcars know as a single can challenge exahst is NOT the challenge race exhaust. Few of you have ever seen a real chalenge exhaust. It is very loud and can be heard for blocks. It is a true race exhaust. It is not even listed in the 1994 challenge parts book but it exists. It is little more than a crossed over set of tuned straight thru tubes with a small resonator. | ||

Where can i get these "Silverstone Chips"? Also, i am in no way trying to compare this cars speed and performance to my Diablo. Im comparing it to my stock 91 Nsx. I want it to be atleast as fast as it is. | ||

I find it hard to believe that a, ECU would give you any more than 5hp, and even that is optimistic. In a N/A car, all it will do is try to bump the timing, but i'd imiagine that the stock one is already calibrated to advance the timing as much as it could before knocking. Car and driver did a test on chips and most cars gained 1-3hp, one car even lost some. | ||

Martin, Regarding the rev limiter. I agree completely. I plan to install the stock ECU's in the spring. My 348 spider versus a 355. I stated the prior owner made this claim. I personally have my doubts. The Ferrari is certainly fast enough for me but doubtful as quick as a 355. I actually do not know or care. My cats are currently out. I installed the tubi test pipes after the emissions test. No test required for 2 years. The car performs flawlessly and sounds like an F1 machine. If the swap is simple, I may dyno the 348 with the stock spider ECU's and the "challange" ECU's to determine any measurable difference. The 348 spider ECU's are different than the earlier 348 ECU. Should be interesting. Having owned several P 930's, I realize reality and perception are quite different. Many 930 owners claim to have 400+ hp and sub 4 sec to 60 machines. Reality is a different matter. | ||

John, scary to have the rev limiter taken out. Uh, that spells engine re-built! I never drive the cars to the rev line but had forgotten to shift on the track once and would have burned the engine then. Scary! Holding up with 355s, I don't know. They are faster, no doubt. Especially with the CATs still in place in your car I can not see how that is going to happen. Now I am the defender of the 348s and take a good argument on every day but I can not see how this is going to happen. Maybe Andretti in a 348 and me in a 355, we'd be running same speeds. Would really like to see what the chip brings in HP. Have you considered taking the CATs out?. If your readings are well below you may want to try that, just for fun. Put test pipes in. I have had a great experience taking my CATs out. We have no emmissions her ein FL anymore but I have heard from others that even without the CATs the cars will be below. Maybe go to one of the indepoendant stations to pre-test before heading for the final smoke test! Allan, I do not think you will be able to get much out of the 348 in terms of power that you will be happy to compare to the Lambo. I mean you are talking two different cars here. A chip will not make you happier, just set you back financially. With that said I have a question on my own: The chip is a new ECU, right? Do you discard the old ECUs and put in the new ones ? When you have a bad ECU can you change them for Superchips at that point? | ||

What are super chips (in the ecu's...?)...? What's a dyno test...? what's tubi, tubi bypass and K&N...? | ||

Allan, My recently purchased 348 spider has "Silverstone Challange" chips installed in the ECU's. According to the original owner, who was the most fanatical Ferrari owner I ever met, these were the chips of choice for the challange race cars. Advertised HP gain etc etc etc. True or not? Never had the car dyno tested. No rev limiter and the car is the quickest, most responsive, well sorted 348 I personally drove. The 348 has tubi, tubi bypass, K&N, and the chips. Owner claimed, at Texas Speedway driver event, this 348 would "stay" with the 355's. Again, true or not? I really do not know or care. I may have the car dyno'd in the spring with the stock spider chips and the "challange" ecu's to establish any gain etc. With the "challange" chips and cats in place, the 348 passed MA dyno emissions test with no problems. All readings well below max levels. | ||

After reading the other post you made you must really be frustrated with the speed of your car! Ever consider trading it in for a challenge spec car? | ||
