Was down at Dr. Forrest surgery today for my 3rd ( a final ? [:P]) remap ......
Roads were bone dry and the air temps were low with exceptionally quiet roads
The car has been transformed into something I am almost scared of now.....
Making 305 bhp & 300 ft. lbs torque and 1.0 bar boost @ 2800 revs ( 1.3 bar by 2950 revs).
I will do my usual Dastek Dyno benchmarking soon for curves comparisons with the previous remaps
Almost exactly the same power and torque than an STi8 with PPP but in a lighter car with
a 5 speed box. ( http://www.prodrive.com/up/03MY%20STi%20PPP.pdf)
I was worried about the turbo being laggy before I got my remap but the fact it that it's more torquey
off boost than with the TD04 fully compensates. The VF35 is on full boost before 3000rpm and on song only 500 rpm later than the TD04.
Where the TD04 went to sleep the VF35 kicks off. At 4000 revs it surges right up to the limiter. 3rd gear is pure shax ...
And then the party piece. Andy enabled the disabled the fuel cut overrun ( or whatever it was called) in the Ecutek software
to let me see ( or should I say hear !) what it was like. Farkin' hall.............sounds just like anti-lag when you lift off ( with a hot exhaust). We were teetering like a couple of schoolboys after a quick sprint and the inevitable pop-bang routine. We are not just talking about the odd random pop - these are full on, guaranteed, on demand and numerous. Sadly I opted to have it disabled as the novelty would have worn off and it was just a bit too frequent. Ecutek really should have the functionality switchable via the aircon button or something. Then their license sales would go nuts
So all in all, the car is running sweet and I am well chuffed. Canny wait to see how she performs at the Ring.
A HUGE thanks go to Andy and Wuz for their combined wizardry ........[Y][<)]
Engine Mods for info :-

• IHI VF35 turbo ( ported to deter boost creep [8-|])
• Walbro fuel pump 255
• TSL WRC Sportscat
• Decatted up-pipe
• Straight through 2.5" pipework
• ScoobySport BB
• K&N Panel filter
• Samco intercoolerhoses
• Recirc DV

Nailing it outta the Forth Road bridge toll was a total gas []

Thanks to all you lot too for generally being a bad influence. Thanks to you jokers I have gone from 215 to 230 to 250 to 305 bhp.

I have a TSL Thundercat which I purchased from WRX_Rich. Think it must be two years old now and is performing just dandy. No probs @ MOT time and now real difference to the fully decatted H&S pipe I used to run........

The TSL pipe mates to a classic style centre section negating the short cat pipe section.

My car is a 2002 WRX ( October) 215 bhp out of the box IIRC.
