Preliminary review

My experience with XRT tuning has been amazing! Previously I was on a Cobb OTS stage 2 tune for my 2008 Legacy GT wagon 5EAT. Although the boost was high, it felt ‘heavy’ and slow to respond in the low to mid throttle range. Ed sent me a preliminary map to show me what it was capable of and wow, very impressive! Light and part throttle response and power is night and day over the Cobb, and he is proving to be a wizard with the 5EAT response! Ed is quick to respond to questions and very interactive. Within two days I’m 2 revisions in already and really enjoying the tuning process!

v4b Customer logs review

Post by west_minist » Tue Oct 31, 2017 7:43 am

OK we are close this one was good!

Town driving--Throttle response is still nice and strong-nothing changed there and that is good. A little jumpy in S# at ~25% throttle around 3K in 2nd and 3rd BUT** it's very responsive to input and i don't have the most steady foot on bumpy roads:-) doesn't do it in S mode so yeah...my foot lol!

3rd gear pull-- Only 1 single instance (single cell) of ping (-1.5) right before peak boost. a few -1.5 cells as I lifted off throttle at 6000rpm. Feels Strong.

How it feels on the 3rd gear pull--pulls harder as the boost spools up--perfect!. It feels like it hits a shot of Nitrous about 4600RPM as it transitions from 8.5degrees to 10.5degrees of timing. It's subtle, not a surge, but I thought I'd point that out.

Roll on acceleration about 3000rpm---amazing in all gears. I don't really feel that transition in this circumstance.

2nd gear is just nuts. I never really tried it before at WOT. SO yeah, nice one!

Shifting--under load, nice and sharp and quick. I don't know if it's possible to tune this----> but it would be nice for the trans to respond faster to paddle inputs, especially at light load around town. No big deal though;-)

V5-Extreme Review

lright, well where do I start? As we are getting close to the end of the tuning process I’m thoroughly impressed. Ed’s knowledge and feedback to my queries has been fantastic. He’s quick to respond and I challenge any tuner to provide such good customer support! Feedback is nearly immediate and revisions come daily (sometimes more often!).

I urge any Cobb tuned customer to consider XRT. If you have an 5EAT or if you are Cobb tuned on Canadian petrol, you need to contact XRT tomorrow!!

My Cobb stage 2 provided predictable, modest power improvements as advertised from Cobb. However, as predicted, the pinging (feedback knock, fine knock learning) was endemic, over all grades of petrol. Only after a couple revisions he had the power far above Cobb’s tune, and a transmission that provides strong, fast shifts. We are onto Rev 5, and the power keeps building and I’m getting zero pinging under all conditions, on standard Canadian 91 petrol! And the shifting and throttle response are unreal. Night and day over an Off The Shelf tune…. BRAVO Edward!!!!
