Hmmmmm I saw 666 bhp in august but I'm booked in for December for version 5 and a dyno tweet as I hate the soot.

What exhaust are you running?

Definitely less soot, in fact I can't see any now.

I'm running a 90mm system...would 102mm gain me much I wonder? I got 661bhp with the 90mm.

Great result chap!!! And ba-Jesus someone fix the sideways image, ah here ya go.

And yes less soot, tried on my ecutek 5 and it's definitely less. They have really done a lot of work on ecutek 5, with the 'noticeable' changes, more power, pops bangs and flames on maps 2, less soot and even better mpg. And they said 640ish was the max power on stock tubbys eh! Ha ha

I got 13 torques and 5bhp increase on the last one going from a recent v4 to v5 on the last one.
This one went from stock to 4.25 in one hit.

Less soot for me on v5 vs v4

What's the likely cost to upgrade from 4.25 to latest v5 map please?
£384 for upgrade and dyno mapping, £120 less for remote mapping.
You should get the dyno mapping and take the opportunity to go SD by moving the temp sensor post intercooler for a small extra charge.

What does "SD" stand for?

Thanks mate, this could well be my first mod! Don't have ECUTek so can't make the saving by mapping remotely sadly.
What do you mean by going 'SD'?

I'll be upgrading from V4 to V5 (Stage 1) with dyno map at my next service.
What would be the benefit of SD over retaining OE MAF;?
Power, efficiency, better MAP, etc?

Speed density
So rather than you knowing the air intake temperature and guessing at the temps going into the engine, the tuner knows the actual temperature post intercooler (and pressure) so can produce a much more accurate map.
This gives extra horses whilst being safer - win/win in my book.
