Until last week I was quite content to leave my daily Bora at a "Stage 2" level of tune, that was until s3dave put his Relentless v3 manifold up for sale.
The hardware is currently as follows: -
SFS 3" TIP w/ Jetex Open Cone
eBay FMIC (To be replaced with a Welly Cooler in a couple of weeks)
Pipewerx 3" DP w/ De-Cat
Milltek 2.75" Resonated Cat-Back
R-Tech Mapped (280bhp / 295lb-ft)
Now that I've bought the Relentless v3 from Dave, if I was to fit that then I'd want my rods doing at the same time so I'd be leaving the car with Bill (Badger5) for rod and manifold fitting. I'd also replace the SFS TIP with a B5 v2.2 TIP.
Niki (R-Tech) suggested if I'm keeping the stock K04-023 then it would be worthwhile to fit an uprated actuator, presumably Forge.
I also understand the benefits of WMI, however I'd rather have my car mapped to run less power and not have to rely on WMI.
The question is, what sort of gains am I going to see from fitting the above?
I'm wondering if I'd be as well going for a beachbuggy hybrid given the work involved in fitting the rods/relentless.
Is WMI essential with a hybrid?
