Hi Adie,

I have a question that I think you will be able to answer...

Today I fitted a BMC-CDA to my car (was used for about a month by another alfa owner, was still clean so I didn't clean it...so no chance of over oiling the filter and killing the MAF).

I did try to clean the MAF myself by using a special spray for that purpose....anyways that is what happens now with the BMC-CDA

The car feels a lot more responsive, turbo lag is less I think and it kind of pulls from lower revs, in fast accelaration turbo lag is non existant ...for example changing from 2nd to 3rd there is no turbo lag at all....BUT

BUT....I made a few drag races today and when I reach 3rd gear at about 3700rpm the car shows motors control system failure and the power is gone....after I press the clutch and then re-engade the gear or another gear everything is good again.

That occured only last summer when outside temperutures were very high...and also it occured after I fitted the FMIC (after the collusion my car has survived)...

As far as I remeber back then it showed something like pressure control (don't remeber corectly)....BUT then I the problem occured when i was about to overtake someone, floor the car to the maximum...I reach just about 3000rpm, release the gas pedal quickly (due to another driver thinking of overtakeing) and then hitting the gas pedal to the floor againg and then it showed the same thing motor control system failure.

What do you think causes the problem??? should I go for another remap, as my car has changed a lot since the original remap on the factory standart car....remap was done by digital tuning...from 115 to 148bhp and 363NM...dyno tested it and it prove their figures....

Now the car has the BMC-CDA, both of the catalityc converters are gone and a free flow sport exhaust is fitted, together with a frount mount intercooler...

What power increase I might be looking at...and should I ask for another remap???

With that setup, do you think a bigger turbo as a must and what performance increase I can look at.

Thanks in advance and sorry for the long post.
