Well it was a funny old day yesterday. I set off with the intention of seeing just exactly what my car would put out on a rolling road. But with every mile closer I got toward my destination, Hurdy's words kept ringing in my ear, "you ought to be running a stage 2 remap with all the other mods you've made"..... And with that came my moment of clarity.
I knew that a stage 2 Evo remap, would be good for 50 ponies, give or take a couple and one thing that had always intrigued me was, 'just how much performance, am I actually getting out of my other mods". So I decided to have the original map put back on the car and to get some results, purely based on the exhaust, inter-cooler, diverter valve and induction system having been added. The only downside to this was, that I wouldn't ever know a true max bhp output. I could however, semi-accurately guesstimate that figure, knowing that a stage 1 Evo remap is good for around 30-33 bhp.
The results were as follows;
Standard Gti = 197bhp / 207lbs-ft. My Gti = 229bhp / 246lbs-ft
I was quite impressed with the 32bhp and 39lbs-ft gained, from my 3 main performance mods. It also meant that I had correctly estimated the overall bhp of the car to be somewhere between 260 and 270.
I was speaking with another customer who was present during my dyno and he was also a mk5 Gti owner. He had dyno'd his Gti the previous month, with almost exactly the same mods, less the I.C and his read out was only 216bhp, meaning he'd only yielded an extra 19bhp from standard!
His exhaust was Magna something or other and his induction kit was a BMC unit. He was surprised to say the least, that my car made an extra 13bhp from the same mods, less the I.C!
Mind you after his recent stage 1 remap from Celtic tuning in Kernow, he busted out an impressive 261bhp on the dyno, an addition of 45bhp from the remap, very healthy, but not quite as much as the 60bhp they quote on their website
Anyway, the end result is that my car has been booked in for a custom remap and possible upgrade of the fuel pump on Tuesday 24th. I've asked politely and am hoping for around a 50bhp gain from the remap, but with more emphasis to be placed on mid range torque between 1800-3400rpm. I'll do my upmost to get on a rr, as soon after the remap as possible. I can't wait to see if Evo can produce what I want. Hopefully the end result will be somewhere in the region 280bhp and 300lbs-ft.
I'm excited beyond belief
