Right i know this is a poo engine compared 99% of the cars on here but im going to work with what i have got

Looking for some power improvements

To date it has

Full mongoose system on it
K+N induction kit with cold air feeds
Jackson Racing throttle body - In the post was £75
stage 1 kent cams - unfitted got them off my mate an they are in great nick
Will try get a remap end of this month at wallace performance

Can you suggest anything else an will i see a improvement with it or have i wasted my money.

Im not clued up on tuning so any help would be great

I only got this last week lol

The plan was to sell the Vectra an get a loan or HP for a big power car but i decided i shouldnt as i cant be arsed paying a car up or a loan an my gf makes everything expensive to insure.

Thanks

Connor
