Hi everyone I'm new on the forum so I apologise if I've posted this in the wrong section. I'm looking for the best way to increase BHP on my Audi A3 1.6 FSI petrol engine. Currently it has 115HP. I've looked at products online, such as this one (Audi A3 (03-on) 1.6 Petrol 40 BHP POWER CHIP & FUEL SAVER - £49.99 : Tuning Wizard - High performance chip upgrades, fuel savers and much more, unleash your vehicles full potential.) but given the low price, I'm assuming it's total ****, and it claims to raise BHP by 40 which seems unlikely for a petrol engine. Also I've looked at remapping the engine (Audi A3 TDi FSi Remapping - Mobile ECU Remap Chip Tuning Yorkshire Discount | eBay) which is more expensive but only boosts horsepower by 13. I would love to get some advice from someone who's more experienced than me (not difficult to meet the criteria). Any suggestions would be greatly appreciated! Many thanks!
