I am doing a bit of research prior to jumping into 355 ownership and have the following questions which I would be most grateful if someone could shed some light on:

1. The 355 is quoted at putting out 375-380bhp in standard form, but do they actually make this power or do they have a tendency to come up short (I'm a TVR owner so I have to ask !) ?.
2. Has anyone any experience of tuning a 355 - in particular ECU re-maps, induction mods & decatting and if so what sort of power and torque gains did they see and more importantly how did it improve the driveability of the car.
3. Do any of the after-market exhausts improve the power output or are they for aural pleasure only ?.

Thanks in advance for any info/help,

Simon

Ive tuned 30+ of these now and several for forum members here.
All Ferrari give less power than standard by about 10-15% on average and tuning can get the power to the quoted stock figures, sometimes slightly more.
Tubi exhausts i have seen work extremely well and ive seen 21hp at max figure and on average i would say they do as they quote.

On your car expect anything from 15-25hp on the remap depending on your fueling requirements.

I have decided to advertise on the forum after one of the PH team contacted my advertising manager.
The new workshop is finally complete other than some final decorating and the place really is something special.
We decided to house the dyno into its own temperature controlled cell which can be held at any temp from 12.5 degrees too 32 degrees meaning we can make many controlled tests on our new 3800hp 4wd dyno.

I hope to post when i have the time as well.

Matey a few answers to your questions as I ahve done all that you are asking to my old 355.

Firstly use only a reputable establishment who deal SPECIFICALLY with Ferrari's - these cars are expensive so its your call but I would recommend only two guys out there - both of whom are well known, verififed and their business is all involved in Italain exotica.

I also was a TVR owner - a 420bhp Cerbera apparently (make that 360 sir). Same is to be said of the 355 in general HOWEVER only a marginal difference has been noted compared to the TVR 'rule of thumb' philosophy !!! Remember the older the car , the way it has been looked after etc...all affect the real BHP. from memory the ealier models (the 2.7 f.i model) had more bhp than the newer (post 1997 5.2 feul injection model) - never really knew why - or cared ....5bhp here or there never bothered me.

Onto the mods then....

Firstly took off stock exhuast as it sounded crap and weighed about half a tonne. Not going to get into arguments about what is best here - plenty of threads on that but I started off with tubi and then took off the cats. Noise better , better throttle response , easier revving

Then I hade the Gruppe M carbon airboxes installed with Uprated air filters adn the Gruppe M rechip. I had it rolling roaded but the result was a disappointing gain of only 20bhp. I then had it remapped again as I bought a different exhasut (for the noise alone) namely an ITO adn upon remapping it came out at 398 bhp..... I ma an ignoramus as to what the torque was but you could tell the difference from the pick up to the torque available lower down the revs.

Bad news is that the whole set up cost me a lot - £3k for Gruppe M airbox , £600 for chip a further £300 for remapping , £1.6k on tubi, £500 on decat pipes, £3k on ITO exhaust , god knows how much in labour n bits n bobs....


Then i went and spent £3k on a big brake upgrade as well.....

Personally - worth every penny..... huge grins, huge smile, quicker car, easier to drive, free revving, bloody loud flame spitting italain whore. Loved her. But then I jsut wanted more so she went and has been replaced by something else now...


My 2 reccomendations ?? Same as 100's of others on here Karl at Verdi Ferrari (only man i have met who can tell you waht is wrong with your car by listening to it over the phone) and Manu & AJ at Scuderia Systems. Yes they are mates and I feel free to promiote them both becasue they are the dogs b*llocks with these cars. If you value your car - send it to people you trust.

Here endeth the lesson

Just registering my interest on this thread so I can refer to it when the times comes!

Basher, I think I recall your car from the classifieds? Red spider with picture of the carbon box in the bay? Looked superb.

Where is it now? Was it a reliable machine?
