Hello, the gains from the remap are very noticeable and can be as much as
16bhp at the flywheel across some parts of the rev range.
The decat would free up a few more horsepower and together they will make a nice difference to the car. The increased rev range will just mean you can hit a higher speed in each gear.
I hope this helps.

Sorry bud, I didn't mean to come across as having a pop at you.
Realistically, I have had my 172 remapped, fitted a Janspped 200 cell sports cat', I have a custom 2.5'' exhaust, a phase 1 172 airbox with Pipercross panel and uprated feeds with silicone bend and I doubt I have hit 185bhp as yet.
Remaps are a worthwhile mod' but don't expect turbo like increases.
PM Pmurray on here as Paul runs RSTuning and can map' your ECU directly from what I remember if you are willing to send it to him.
