Chips & Power boost valves

[BurdeG]

I would like to gauge responses & feeling about the subject of ''chips'' and not the kind you put salt & vinegar on!! & power boost valves. My previous sportscars have not been ECU managed and so Ive played around with cams and heads & carbs. But now my S2 is running well I would like to perhaps give it just a little more power and pull, perhaps looking for say 185 or 190 Hp instead of its 168 (cant afford to upgrade chasis / brakes etc so dont want to go too mad you see - but I am replacing shocks & springs) Please can you give me any info / advice about both Chipping of the ECU and/or fitting a PSE power boost valve and what results would be gained. Thaks very much Giles

Thanks. Yes the Power Boost Valve increases the fuel pressure as you apply more throttle and therefore provides stronger torque & pull in high gears. I know someone who has one fitted & says its the best mod he's done! Giles
