I dunno mate, that's straight off the timeslip!
I haven't got them in front of my now but I think there were a few runs around 93? Fordfreak I have the same issue with 3rd gear - if you hold it out you'd gonna hit the limiter in 3rd otherwise you've barely into 4th as you cross the traps. If you run slightly lower profile tyres you get through the gears that little big quicker. I'm up for new tyres shortly and I'm gonna try and squeeze some 355s on my rims. That should give more traction off the line and a bit lower profile in height too (as a function of the width, it's just the way it works out) 175rwkw seems to be eating through my clutch though. I can't hold 2nd gear burnouts anymore because the clutch slips. It's still fine on the street though so not worth replacing yet just for a better ET. What did you pull on the autotech dyno prior to tuning ? I assume it was dyno dynamics ? I only did a low 150 at powercruise a few weeks back, although the engine was pretty hot after belting around the track

haha, typo! that should have been 255s
I don't flat change as such, I'm reasonably nice with the gear changes although 3rd to 4th is very quick anyway. I shift on redline

my timeslip... on my road tyres... 235/45/18s... so you mean try a 225-255/60/15 or something close to that hyena? on the back wheels... could bolt up light 205/60/15 to the front for less rolling weight n wind resistance... figured out it might be my coil pack thats givving my engine a slight miss between 1400-2500 rpm at up to half throttle applications... not sure of the before figure prior to the tune but after Spiro did the dyno tuning the car definatly felt just a lil more athletic through the gears... not sure about the dyno manufacturer... must be good though cos Granville autotech have a pretty good buisiness... and alot of happy customers...

I couldn't be a*** putting skinny wheels on the front and really I think that's a bit of a toss unless you're running times a good few seconds less than us. But yeah on the back the last time I went my burnout rims were something like 185-55-15 or something. The skinny width and lower profile made for a pretty tame launch because you couldn't rev it up much but the smaller rolling diametre made up for it a little once moving and made it a bit quicker through the gears

i definatly like my 2.0 sec 60 footers... but they were with my 235/45/18s... might have to search around for some chunky lil tyres for the a** end... you'd suggest something like? eg) 225/60/15? i can get those tyres easy.... i already have the rims...15's that is...

Go to American Autos, get some 235/60/15 Drag T/A's. Street legal Semi-Slicks, and a set of EB XR6 15in rims, then they sit under the gaurds nicely, and trust me you wont have any traction issues with these. I paid 240 each about 2 months ago.

Chasers are 15/6, EB XR are 15/7
Thats all. In theory you need a 7.5 to 8 inch rim for the tyres Brett

That is the biggest number I have seen from a i6 on Spiros dyno in NA form. I guarantee that you have a 14.4- 14.2 in there. I ran a 15.19 with 131 rwkws from the same dyno.
