What would you rather have, a bike that sounds amazing and doesn't run right, or one that sounds good and runs well?

Choice 1) isn't guaranteed - you could spend a lot of money and still not get it right.

In fact, I'll do a sound clip of the Tubbs mod tonight when I pick up my bike from my pal's (no drinkie/drivie!) - got a nice field recorder I use for recording band practises.

I felt that with the Tubbs mod the bike had a little more power - front wheel started coming up earlier. This may be cos he runs a dyno shop and tested the exhausts there - dunno for sure though, suppose you'd have to ask the man.

Who's that for?

I don't know what bike you have pre 2008 or post 2008?

Sound clip would be brilliant! I videod my bike last night but the camera can't handle the deep roar!

I've got a 2007.
Had to mess around with ECMspy a lot with my Termi and still never got it right.

With the Tubbs one I just stuck it on and it ran fine with the map I had for the Termi (basically cutting down fuel about 15% in the overrun area).

Actually thinking about it, I should really got back to the map it came with out of the factory...

O forgot to say that I've noticed my bike takes longer to start when cold now? Any reason for that?

Maybe it's losing the will to live...

Why wouldn't you want it popping on overrun, think your looking for the golden fleece bud, my zx6r also pops a lot on over run, it did when it was new and standard, it really does now it's not.
I have a freespirits system on my uly,(mine is an 08) I've answered your previous post/question on this very subject, you need a freespirits fueller and even then it won't be perfect just because it won't.
It's standard ecm is trying to make your engine put out very exact emissions even at the cost of it running shit everywhere else, (the post 08 are the worst for this I believe) the freespirits will get you around this, I watched it do it to mine on a rolling road.

If all else fails though, buy a Honda.

I've been thinking about a tfi unit today. It's doing my head in now! Which way do I go cause I don't have the funds to change direction! From my perspective it's all unknown and potentially really expensive!

The popping thing to this extent is new. I'm not against popping but it's much louder than it once was and more frequent, and I'm not keen!

Not sure I'm looking for the golden fleece, but my inexperience is leeding me blind!

I've read that some have race ECM, exhaust, k+n and powerizer! Isn't that redundent with a race ECM?

how the f**k can all that cost you less than a tfi fueller £200 all done, nothing else to sort, buy one if its a load of shit put it in the for sale section and you'll lose £30.00, simples.

TFI fueler

Well if that's true then it's worth taking a chance! I would probably fit and then have it setup on dyno

Air leak into the exhaust will make things worse regards popping/fuelling. Headers to silencer sleeve joint sealed?

You want to hear this pop on the over run, it's ace
