Can't hurt.
Back in the day, when AmD wasn't anything to do with BBT they offered this all singing, all dancing stage 2 kit for the MKIV R32 remap/induction/Milltek & Sportcats/etc cost a bloody fortune.
Anyway, one of the Golf mags held a 1/4 mile shoot out and he rocked up in his R32 and lined up with all these other modded N/A cars they'd sourced. Stage 2s, cams and all other manner of things... but no chargers/turbos. He pulled the battery, shoved a few bottles of octane booster in, would the timing forward with VAGCOM and took it for a spin up and down the straight.... and absolutely monstered every car there.
£20 and a 15 minutes work battered thousands of pounds worth of mods, there were some very annoyed customers complaining as you can imagine.
