I've got a 2001 2.7l Tip with a superchips (brand) ecu remap.
Frankly, the main difference is a smoother engine that is more willing to rev up, with alittle bit better power. It's supposed to have better fuel consumption but I've not really notice that (maybe it's better if I stay in the lower rpm range vs b4 the remap).
I don't think the "additional" power (assumption) is going to stress the tip box. Supposed to have an additional 10bhp.
Your mechanic may be right if it was a turbo.... I had a massive 70bhp increase in power on a custom remap on a prev turbo car. The gearbox protested against the increase, but surprisingly survived the 3 yrs I had the car.
A remap or add-on chip will void warranty but I don't think it's a concern for most of us here as most of these car's warranty would have ended long ago (unless u have a new replacement engine from Porsche maybe)
Is the ecu remap worth it ? Well, if you didn't have to pay much for it, it helps alittle. The IPD plenum with larger TB gave me much more results but that's bigger $.
