Yes...just chipped it.
The most significant mod is the rev limiter set to 7250 rpm´s.
It´s usefull when racing because despite you´re not getting more power after 6000rpm, you can push it further just between corners.
With this I mean you don´t have to change gear just before a corner just because you hit the rev limiter.
Sorry about my english

Why only 7350?
And why exactly 7350?

Sorry Mats...it´s 7250 rpms.
When my "ECU tuner" was doing my chip program he asked me how many revs I wanted above stock rev limiter and I just said a plain 500rpm´s
6750+500=7250rpm´s

500 or 600?
Mats, what is your car's rev limit?
I'm only revving my car to 6500 rpm. I'm paranoid about it sticking a rod out the block.

Knowing that I´m running on stock pistons/rods/cams, is it dangerous to go furter than 7000rpm´s?

You know, my friend had a GTV6 2.5 with stock bottom, modified ECU and just QV cams. He revved that thing to 7.2K rpm nearly everyday, and at least a few times a day. Nothing happened to it. I'm sure you will wear it out quicker than if you were to drive it up to 6.5K rpm only, but otherwise it was still very much alive years later. Maybe I'm just paranoid about these things.

Rev limit?
Dude, I don't even have a reliable tach right now. Luckily I have my fantastic ear and in perfect sync with my calibrated seat-of-pants dyno I just shift gear when the engine fall off cam, sounds like 7500ish but maybe it's more.
Std cams so it really doesn't pay to rev it too much.

Yeah Mats...you´re right.
I´m not pushing it further than stock 6750 because there is no power after that...I would better say "there is no power after 6000rpm´s"
Cams have to come

fast...what do you use on your Alfetta racer?
