nah thats the weird thing, its not mafless tuned. it might have a maf tune though, and im running a custom otr with the maf and when i get a mafless tune the maf metre just gets replaced by silicone hose

So how much power would a set of high flow cats and a mafless tune give me? something like 40rwkw more?

I wood agree, 10-15 at the most and you must have already got a tune done like a MAF custom edit. With these standard bolt ons I would say 230 plus at the wheels. Upgrade the valve springs as the stock ones tend to chatter a bit might get you another 5kw. If you want the at 270 at the wheels better get a cam done.

All tuners are different, results will vary on any dyno but with stock mods mentioned above with a stock clutch I think you get some good results.

Happy dynos. Full exhaust (headers, cats & pipes) with OTRCAI and mafless tune will get you between 220rwkw & 240rwkw.

Hold on, so no OTR CAI an you pulling 253 at the wheels from a 5.7, is the dyno the calibrated properly.

You need to give the full picture or people will call your figure BS.
