Chipping JTS Motor

Can this be done to get a bit more mid range power?

Not worth it. You will get VERY marginal gains on JTS engines. The only engines worth tuning are diesels as then you can see some truly noticeable gains. Save your money and invest it in better suspension or handling components. It will give you much better real world benefit than tuning a stock JTS.

You can get it remapped by someone like Gus at AlfaTune.

Im getting mines done this Saturday. Donít think it'll give you massive amounts of extra BHP but from reading reviews on here it makes the car a whole lot more drivable, eliminates flat spots etc.

If you Google JTS + GUS + remap it'll link you to the threads on here,.

These guys seem pretty happy with the results.

yes there are gains to be had you will get around 10-13 bhp with our map and an extra 12 lb/ft of torque so not to be sniffed at, yes you don't get gains like a turbo diesel but still better than standard

Hi yes we have a great file for those, on this model we raise the rev limit by 500 rpm and correct the fueling and ignition tables to raise power to approx. 262 bhp and torque raises from 213lb/f to approx 237 bl/ft :-)

Sounds good to me, few more little jobs to sort and then a remap it will be (if I don't sell it...two minds)

have two GTs

one is a chipped diesel that is used for commuting every day

the other is a mint low milage jts that only gets occasional use but has a few flat spots hence wanting more mid range

also got a 3.2 spider for serious horsepower

What kind of gains for a GT 3.2 with wizard manifolds and cat back system? Anything else I should do first? And what's it likely to cost?

you will see an increase with the manifolds on top of the remap how much it gains depends on the condition of your engine , eg wear etc we don't b---**** people with laughable figures, all our experience of building and running some of the best alfa racing cars in the country have shown us every car is different,
