Just as slow as before my mods..

Haven't read 5 pages, so might have already been mentioned:
- chirping tyres requires low end tq
- headers with too large primaries will kill low end tq & even correct size pipes does not guarantee a power increase...
- as will a cam that is too big...
- alum intake does mean more low end tq
- the bigger diff might have consumed the small hp increase in friction
