Anyone ever chipped(changed the ecu) a 355? Who does it? Power bands changed alot?
Many posts on this topic the last 2 weeks... Summary - Chipping the 355 really doen't buy you much - you will lose on the top end power range or bottom - so not really any true benefits... Do a quick search (top right menu option)
Other things you can do:
Mass Flow Carbon Air Intakes (or something like that - takes place of your Air intakes with carbon fiber better flow thingy)
Replace Seats and other heavy things with Carbon Fiber to lighten the car
Put Shields on the sides - this seems to give and extra 50hp
You can try Total Performance - They are a FCA advertiser.
They have an ECU upgrade for a 355. They show 22+HP for $595

I had the Total Performance chip and it didn't seem to do much. I bought a Challenge chip a few years ago and that did make a difference. More midrange power and I did not loose anything on top or bottom. I also have the GruppeM intake Hyperflow cats and Tubi. Compared to other F355's I have driven and others who have driven mine, it is much quicker. You have to keep the revs up on these cars. Driving above 4500 in any gear will give good acceleration. I think people tend to drive Ferraris like they are Vipers. There is really no good acceleration below 4500-5000rpm
Where did you get your challenge chip and if you don't mind what do they cost? I have a challenge muffler on my 98 355 and it gives a nice sound. I once considered the challenge brake chip($1500) I think but learned that it is designed for the track and changes the character of the ABS brakes. the engine chip sounds interesting. Thanks.
Anyone seen dyno figures on any of these chips? I wouldn't spend the dough unless I could see actual results.
Oh yes, I noticed you get the claimed 50 HP but only when parked. That is a great addition to any Fcar!
I got the chip from Auto Sport Design in New York. I got it several years ago and it was the last set they had. They ran several Challenge cars. The cost was $900 and also got the rear air scoop that fits over the clutch housing and F40 front brakes and rotors from them. The chip made a difference right away compared to the Total Performance chip which didn't feel like it did anything other than raise the rev limit 500rpms
Does your car have the 2.7 or 5.2 Motronic? thanks.
It has the 2.7 It is a 95 F355
Sam, do you mind telling me where you got the challenge muffler? They are the best sounding v8 set up I have heard. thanks, John
I had a customer install tubi test pipes, tubi exhaust and aftermarket air filters along with having his ecu reprogramed. He said it was two different cars. So much more mid-range and top-end power. He said he was going to go look for 360's..... so needless to say, I think he was happy.
I have a 5.2 355, I'm finding it difficult to locate a decent chip for it.
What I'm really looking for is a over-run chip (more flames!!!), does anyone know a good supplier of over-run chips for the 5.2 ??
Not so fussed about the Rev limit increase to 9500, but if there is a chip that does that too - all well and good!!
