GR Yaris ECU solution .... Is it real???

It’s early days with the GR but it seems to be well-engineered and, going on historical evidence from almost every other similar type of car, I doubt there would be much/any effect on long-term reliability from a 10-15% tickle, so around 300-310 hp at the crank.

You can liberate a fair bit of extra shove without pushing the top-end figure beyond that, things like a downpipe and intake will make it feel a lot faster midrange without putting undue stress on anything.
 
How much can we push the engine, clutch and other parts before problems starts showing up. I want to get more poser but i always get a feeling of " will it break, will it break?" when tuning my cars. Now i want to drive around and feel safe with everything. Stay stock is maybe the boring answer 😉
You can drive mine and see if you like it... On condition I can drive yours :D

'Poser' is a quite funny typo, mine is the opposite, not much more power to impress at the pub, but maybe better to drive and should be very reliable ...

It was for a customer in Italy.

The TTE, Kelford Springs and Cams etc is proving to be a popular set up. There are a few cars in the UK running this set up too.

We do know Tony at AGs, he is a top bloke and no doubt has done an amazing job on your car.

There are so many variables when measuring power on a chassis dyno so figures will always vary but your power level is what we and others are seeing with that spec. I think you have more than enough power and anymore will probably result in losing some driveability on the road and on track. It would only be worth pushing for more power if you were chasing 1/4 mile times which let's be honest, it's not really what the GR was intended for. Personally, I'd keep it where it is now with your spec as it's definitely the sweet spot.

We were looking to go TTE with our car but they have temporarily discontinued the GR hybrid turbo while they make changes to it and will release a new version. I'm not sure exactly what they're changing though.
TTE have changed their previous 'TTE400' Turbo to the new 'TTE500' which I suspect will be on par with the likes of a G25-550 for anyone who is interested in going down the Hybrid Turbo route.

And they are still talking about "We also replace the original thrust bearing for TTE upgrade 360 deg that is made in-house." on a ball bearing turbo. What core does one get?

Best to contact them for clarification. We got in touch with them and it turns out they just changed the name. It's the same turbo as the previous TTE400 unit which they have sold many of.

Hard to see that they have customers reaching 500 with this turbo without a lot of the other stuff around the engine...
 
Hi,

Any big difference between TTE-500 and Fensport Stage 3? lower rpm response etc?
