They can help on the right car, with the right resistor. Its not a case of buying one off ebay though, there is a way of working out the right resistor!

From what I understand overfueling wont cause detonation, not like running lean will anyway.

If it ran really lumpy with it fitted why didn't you take it off?

They will also hill your sparkplugs in a short ammount of time, it's basically like running a carb engine with the choke on permenantly... You wouldn't do that. Superchips are mostly a load of crap, so thier 'cheaper alternative' must be a load of shite!

Bought one of these resistors and it fcuked my engine after awhile. ran really lumpy then the head gasket went(dunno if was related to the resistor)

ooooh, sounds like fun
i'm gonna get me one of them

They are a small 5 pence resistor you can buy from Maplin, the fool your engine into running rich by making it think that the air going into the engine is very dense and cold. This in no way will increase the horsepower of an engine, would you put bigger injectors into a standard engine to get it to go faster? No. It will just over fuel and confuse the ECU which will make the engine run very lean every so often... This kind of thing can theoretically cause detination in the engine which aint good...

See them all the time on ebay. Basically i think it screws the engine up after a while

dunno, probably. would that give you more bhp then?

Isnt this just a resistor that can be bought for 10p?

pay on a debit card, and only have a fiver in the account with no overdraft

i know but i was mroe worried about my credit card details if theyre like just a fake ass scam idea

slighty unconvinced, but buy one and tell us how it is, you cant go wrong for a 5er can you?

lol....hmmm
so probly not then? seems a bit cheap for sumthign that wud give that much of an increase

Yeah, get 5 and have an extra 100bhp.

Is this any gud???
