how do you mean with regards to ignition management? can i not use the existing spark from the ecu coupled with the carbs that are manually tuned?

what sort of budget would i be looking at to get betweensay 160-170ish bhp from the standard 150ish?

im wondering if there is anything i can do with the money i have to make a start or if its better to save a lump some and do it all at once.

i apreciate with the mods done and a chip i will be looking at little more than standard power.

does removing the egr off of the manifold make much difference? as i hear they choke up/stranggle the engine a wee bit.

thanks for the reply
