Has anybody used the below chips?
Sounds good to get 200bhp from the car at 8psi. Especially as I could probably up that to 12psi without pinging or pre det.

Cheers

Never used or even seen that sellers chips before so can't comment there.

I do have a set of Stage 1 chips I'd let go for half what that sellers asking if any good to you.

Do you have a gold EZK or a black boxed EZK with the daughterboard mod? Not all EZK are chippable FYI - All fuel ECU chippable. Sorry if you know already!

With what you have done changing chips is not going to improve anything for you. You chip to match modifications

Also in that listing i could not see mention of selecting the right ECU group as you need to use a chip of teh correct group to the ECU you have or it will not work

What extra power and torque will your stage 1 chips give?

Surely they work the same as any other chip tuning. By altering the fuel and ignition maps :confused_smile:

I need to start selling my own chips, most on the market are rubbish! I would actually show the fuel and ignition maps and any other changes.

After a thorough service and replacing all maintenence items:

Level 1 includes my chips, 3" decatted exhaust, M cam, and 13psi gives around 220hp and 320nm. This is good enough to be quicker than an 850 T5m 30-50 (2.1 vs 2.6), 30-70 (6.7 vs 7.0), and 30-80 (9.0 vs 9.3), according to dragy/vbox data.

Stage 2 requires the previous mods, plus an intercooler (a decent one, not an ebay special), a camshaft with more lift and duration like a V cam, and 15psi. The stock intercooler particularly is quite a big limitation, so changing that allows the last few hp from the stock turbo, 240hp and 340nm.

Phase 3 requires the previous mods, plus injectors and changing the stock 13c turbo for a 15g, this will then allow mapping to 265hp and 360nm.

Tier 4 requires the previous mods, plus a 3" maf and changing the 15g to a 19t, which would allow mapping to 300hp and 390nm.



Yeah, it's a ridiculously simple system really, unlike an aftermarket EMS where you can change everything.

Remapping on modern cars is often all that is needed to increase power as the turbo is electronically controlled so boost can be increased via the ECU

So you are saying that Volvo, from the factory got all the horsepower and torque from the factory set up. And there is no positive effect to adjusting these at all?

Even N/A cars benefit slightly from ignition and fuel maps.
