Alfa GTV V6 Remap?

Hi Guys,

Has any of you remapped a 3.0 V6 24v 6 Speed? How much BHP and Torque did you have before and after, also are there any other small mods that you have done and proved successful on rolling road.

Thanks

Im sure there must be one person on here who has had it remapped or chipped.

My 156 has a GTV engine, with a Dastek Unichip mapped for 97 octane fuel, and with a BMC CDA it made 245bhp. Thats also with the exhaust manifolds from a 2.5 V6..

so what's the difference between the manifolds?

Actually, regarding the manifolds I'm not sure if there is a difference between engine sizes. Its whether its Euro 2 or Euro 3 emissions compliant that matters. If your car is Euro 3, it will have cats in the exhaust manifolds. If its euro 2 it won't..

Chris155 on here has fitted euro 2 manifolds (from a vintage 156 2.5 V6) to his 156 (which has a GTA engine) apparently this helps a lot with top end power.

Ah, I've already got em then.. The beauty of having a less environmentally conscious car! Does removing the main cat make a difference too then?

Yeah it will do.. Its something I thought about, but as I already have a straight through centre section I was worried about the noise. I enquired at my local PowerFlow about the price of getting a silenced de-cat pipe made up and they wanted £110 I think, said no chance, robbin' barstewards

I think mine may have been remapped as it revs up to 7200, whereas am I right in thinking 7000 is the usual limit??
